#Multivariate Quantitative Research Methods

[psychwritings]

Stephen Olejnik ends his paper summarizing the methodological steps necessary in multivariate analysis of variance with this quote:

"...good research introduces at least as many questions as it answers."

For those of us currently doing psychological research, I thought this was an important point for us to keep in mind. We can only do so much in one paper, but what we leave for readers to uncover next is also of extreme importance, if not equally important to the results of the current study.

If any followers are looking for more statistical guidance, let me know. I am happy to provide resources for different methods commonly used across psychological research.

ANCOVA and MANOVA ANCOVA or MANOVA A multivariate analysis of variance (MONOVA) is a statistical procedure for comparing a the population means of several groups and when two or more dependent variables exist ("StatSoft," 2011). One of the strengths of a MONOVA is that individual p-values are produced for each dependent variable. This enables a comparison of the levels of significance of the variables, and can show interactions among the dependent variables ("StatSoft," 2011). It is also possible to determine if changes to the independent variables will create significant effects on the dependent variables ("StatSoft," 2011). If we consider the question about the influence of course delivery methods on the academic performance of students enrolled in statistics classes, we may find a MONOVA approach to be of assistance in our analysis. Recall that the three course delivery methods are: online, face-to-face, and hybrid. The course delivery methods are the independent variable and the statistical learning of the students is the dependent variable. Generally, when the topic of a research study is student learning -- not simply performance on a single assessment -- we are interested in pre-test and post-test scores. Adding a repeated measures component to the research design can clarify the extent of learning that students achieved. Another independent variable added to this analysis is college major, and number of mathematics courses taken previously. Moreover, a second dependent variable is tutoring requests during the course, and a third dependent variable is feelings about the course (distress or confidence) as rated by a Likert scale administered as an add-on to each test. Through this addition, the MANOVA can assist the analysis of the three types of course delivery with regard to effectiveness with students at various levels of competency. With these changes -- to a MANOVA approach and the addition of another independent variable (entry level of statistics knowledge) -- we are ready to articulate the research question and hypotheses. RQ1: How are the various course delivery methods related to students' pre- and post- statistics skills? The corresponding null and alternative hypotheses would be: H0: there are no discernable differences in pre- and post- statistics scores for course delivery methods H1: there are significant differences in pre- and post- statistics scores for course delivery methods RQ2: How are the various course delivery methods related to students' perceptions of stress or confidence? The corresponding null and alternative hypotheses would be: H0: there are no discernable differences in course delivery methods and students' perceptions of stress or confidence H1: there are significant differences in the relation of SST scores to perceptions of stress or confidence RQ3: How are students' SST scores related to their college majors? The corresponding null and alternative hypotheses would be: H0: there are no discernable differences in SST scores and college majors H1: there are significant differences in SST scores and college majors As before, the dependent variable reflects learning of statistical skills and may be measured as a quantitative, interval variable through a structural skills test (SST), which is a 100-item test rating the test scores of students on a scale of 1 to 100. However, in this version of the research design, the SST will be administered to students on the first and last days of the courses, regardless of course delivery type. Because several variables are used in this MONOVA analysis, and the analysis will report effects for each variable, it will be helpful to consider how the variables might interact or correlate with other variables. A MANOVA works well when the dependent variables are correlated to a certain degree, but if they are too highly correlated, they may be measuring the same construct. A MANOVA has the same difficulties with regard to multiple post hoc comparisons as ANOVA. Essentially, MANCOVA is an extension of ANCOVR, but the dependent variables are adjusted for difference in covariates thereby reducing the error "noise." Part 2: Racism is pervasive in many societies and resists the efforts of people to eradicate it from the cultural practices and mindsets of many people in a population. Among the many negative outcomes of racism, one of the most important is the impact that perceived racism has on the very people against whom the racism is directed -- or the groups to which they belong. While it is natural to assume that the psychological and physiological outcomes of perceived prejudice have adverse effects on the perceivers, little research exists to demonstrate these relationships. Pieterse, et al. (2012) conducted a meta-analysis review of 66 studies (which means that the sample size was 18,140) conducted during the period from January 1996 to April 2011 in an effort to better understand the relation between racism and mental health in Black Americans. The research question and the research hypotheses are listed below: R1: What is the magnitude of the relation between perceived racism and mental health among Black Americans. H0: no relation exists between perceived racism and mental health among Black Americans H1: a relation does exists between perceived racism and mental health among Black Americans The search generated 138 empirical studies which were further scrutinized for inclusion criteria and sufficient statistical information to productively determine effect sizes. The researchers conducted a search of the literature using the following inclusion criteria: The studies needed to have a specific analysis of indicators of mental health and perceived racism. The studies also needed to focus on subjects who were Black Americans living in the United States. Moreover, the studies had to have been dissertations or published in peer-reviewed journals between the years of 1996 and 2011. A coding protocol and coder training manual were developed; university students were trained to code the dissertation articles and dissertations, and inter-rater reliability of 90% was achieved. Five moderator variables were identified: Racism scale type was a measure of the frequency of perceived prejudicial events and the associated level of stress. Measurement precision was the reported reliability estimate on the racism scale. Sample type indicated whether the subjects were from the community, colleges, or combined. Publication type indicated whether the study was from a dissertation or an article from a peer-reviewed journal. Outcome type indicated the effect size for mental health clusters: anxiety or depression; psychiatric symptoms; life satisfaction or self-esteem; and general distress. Effect sizes were measured by the Pearson product-moment correlation in order to indicate positive correlations between perceived racism and mental distress. Using a random effects model, the effects from the studies were aggregated for overall effect size and weighted contributions of each study. The researches checked for publication bias by using a funnel plot, which is an artifact of published works tending to contain larger samples and significant effect sizes. The aggregated correlation between perceived racism and psychological distress was determined for 66 studies by using a random effects model. The correlation was found to be significant at r = 20, confidence interval (CI) .95 (0.17, 0.22). Egger's regression concept was not significant, indicating a lack of bias (t (64) = 1.01, p = 32, 95% CI (0.61, 1.85). The null hypothesis was rejected. The link between perceived discrimination (racism) and mental health was documented for Black Americans. The researchers conducted a robust meta-analysis review of a large sample of research studies that examined the relation between perceived racism and mental health in Black Americans. Several statistical processes were used to test for biases or assumptions, including the effect of publication. The studies included in the analysis were characterized by measures that indicated acceptable reliability estimates, which further strengthened the aggregate research findings. The relationship between perceived racism and mental health for Black Americans was robust, and was not significantly moderated by sample type, publication type, and racism scale. The researchers recommend future studies to examine the effect of racial bias that is less easily observed -- such as structural, institutionalized, or internalized bias -- as well as more indicators specific to contexts such as workplaces or religious and educational institutions. The meta-analysis of 66 studies showed a moderation effect for psychological distress, with anxiety, depression, and other psychiatric symptoms for Black Americans who perceive racism. The association between mental illness and quality of life indicators was considerably weaker. Moreover, moderation effects were not found for measurement precision, racism scale, sample type, or type of publication. The current meta-analysis supports the concept that adverse psychological outcomes are associated with perceived racism in Black Americans. References Carey, G. (1998).

Building a Robust Quantitative Analysis Framework: Strategies for Success

Quantitative analysis is a powerful tool used across various fields, from finance and economics to healthcare and social sciences. It involves applying mathematical and statistical techniques to assess patterns, make predictions, and inform decision-making. A well-structured quantitative analysis framework serves as the foundation for drawing accurate conclusions and ensuring the validity of results. Developing such a framework is a systematic process that requires thoughtful consideration of data sources, methodology, and analytical tools. This article explores key strategies and steps in developing a robust quantitative analysis framework.

Identifying the Purpose and Scope

The first step in developing a quantitative analysis framework is clearly defining the purpose and scope of the analysis. This phase involves determining the problem you aim to solve, the questions you want to answer, and the overall objective of your research or project. For example, in a financial context, the goal might be to forecast stock market trends or assess risk factors associated with investment portfolios. In public health, the purpose could be to analyze the impact of an intervention on disease outcomes. Establishing a clear objective ensures that the framework aligns with the goals and that the analysis remains focused and relevant.

Once the purpose is clear, it’s essential to define the scope of the study. This includes identifying the specific variables, time frame, and geographic region or population under study. A well-defined scope prevents analysis from becoming too broad or too narrow, ensuring you capture the necessary data to address your research question while avoiding irrelevant information.

Data Collection and Preparation

Data collection is one of the most crucial aspects of any quantitative analysis. The accuracy and reliability of your results depend on the quality of the data you collect. Depending on the nature of your analysis, you may collect data from primary sources (such as surveys, experiments, or interviews) or secondary sources (such as government reports, academic studies, or commercial data).

Once the data is collected, it must undergo a thorough preparation process. This includes cleaning and transforming the raw data into a format suitable for analysis. Data cleaning typically involves removing duplicates, addressing missing values, and correcting inconsistencies. For instance, if you’re analyzing customer behavior, you may need to standardize data points like purchase amounts or dates. Data transformation may also involve normalizing values or converting categorical data into numerical formats.

The data preparation stage also includes exploratory data analysis (EDA). This step helps to understand the essential characteristics of the dataset, identify outliers, and detect any patterns or correlations that could influence the analysis. EDA is crucial in ensuring that the data is ready for the more sophisticated statistical techniques to follow.

Selecting the Analytical Methodology

Choosing the correct methodology is critical to the success of the quantitative analysis. Various statistical methods are available, and the choice depends on the research question, the type of data, and the desired outcome.

For example, regression analysis might be appropriate if the goal is to predict future outcomes based on historical data. This method models the relationship between a dependent variable and one or more independent variables. For instance, you might use linear regression to predict sales based on advertising expenditures or customer demographics.

If the objective is to explore associations or relationships between multiple variables, correlation analysis can help determine the strength and direction of these relationships. In some cases, multivariate analysis may be required to account for various factors simultaneously.

Another key decision is whether to use parametric or non-parametric methods. Parametric methods assume that the data follows a specific distribution, such as the normal distribution, and are often used when this assumption holds true. Non-parametric methods, on the other hand, are more flexible and do not require distributional assumptions, making them suitable for skewed or outliers data.

Model Building and Validation

Once the methodology is selected, the next step is model building. This involves constructing a mathematical or statistical model based on the chosen method using the prepared data. For example, in a predictive model, you would fit the model to the historical data and use it to estimate future outcomes.

Model validation is an essential step in ensuring the accuracy and reliability of your results. Validation typically involves splitting the data into training and testing sets. The model is first trained on the training set, and then its performance is tested on the testing set to evaluate its predictive power. Standard validation techniques include cross-validation, where the data is divided into multiple subsets, and bootstrapping, which involves repeatedly resampling the data.

Additionally, it’s essential to evaluate the model’s goodness of fit. For regression models, standard metrics include R-squared, which measures how well the independent variables explain the variability in the dependent variable, and Mean Squared Error (MSE), which gauges the average error in predictions.

Interpreting Results and Drawing Conclusions

The final step in quantitative analysis is interpreting the results and concluding. At this stage, the analyst must carefully examine the outputs of the statistical models and assess their significance to the research questions. Statistical tests, such as p-values and confidence intervals, help determine whether the results are statistically significant and whether they can be generalized to a broader population.

In addition to statistical significance, analysts must also consider the practical relevance of the findings. For instance, while a result may be statistically significant, its effect size might be too small to impact decision-making. Therefore, it’s essential to evaluate the results within the context of the problem and consider their implications for policy, business strategy, or other relevant areas.

Once the results are interpreted, it’s crucial to communicate the findings effectively to stakeholders. Clear visualization of the data and concise and understandable summaries of the results help ensure that the analysis can inform decision-making and lead to actionable insights.

Continuous Improvement and Adaptation

Quantitative analysis is not a one-time process but a continuous refinement and adaptation cycle. As new data becomes available or the problem scope evolves, the framework may need to be updated. Regular reassessment of the methodology, data sources, and models ensures the analysis remains relevant and accurate.

Furthermore, ongoing learning and development in statistical techniques and analytical tools contribute to enhancing future analysis. Staying informed about the latest advancements in quantitative methods ensures that analysts can apply the most effective approaches to address emerging challenges.

Developing a quantitative analysis framework involves a combination of clear goal-setting, careful data preparation, appropriate methodological choices, and rigorous model validation. By following a structured process, analysts can ensure that their findings are scientifically sound and practically beneficial, driving informed decisions and advancing knowledge in their field.

SPSS Help for Social Science Students in Analyzing Survey Data

Data analysis is much needed skill to be acquired for any social science student especially for those in research and surveys. One of the most widely used programs for this purpose is SPSS (Statistical Package for the Social Sciences). SPSS is adopted in academies and professions for the reliability of the statistical functionalities and ease of use of the application. This post aims to spss help for students pursuing social science courses and are seeking guidance on the use of SPSS for data analysis. We will discuss the basics of SPSS, how spss has become an important tool for research in social sciences, common difficulties that student face in spss and some helpful solutions to overcome these difficulties.

What is SPSS?

SPSS is an acronym for ‘Statistical Package for the Social Sciences’. It is one of the most popular statistical analysis software, designed for handling quantitative data. The SPSS was developed by Norman H. Nie, C. Hadlai Hull, and Dale H. Bent in the 1960s as a statistical package for the social science disciplines. It has developed into one of the most important and versatile tools of data analysis for use by researchers, academicians, and professionals in areas such as psychology, sociology, political science, public health and marketing. SPSS provides robust statistical operations like descriptive stats, bivariate statistics, linear regression, multivariate regression and many other functions. It gives the capability to import, process, and analyze data, test hypothesis, and generate comprehensive reports with tables and graphs.

Importance of SPSS in Social Science Research

In social science research, studying people’s behavior, societal trends, and social phenomena may involve gathering and evaluating complex collection of data. This is where SPSS is most useful as it makes analysis and generating the results in no time so that the researcher can devote more time towards identifying the patterns and finding insights.

Why SPSS is Preferred in Social Sciences:

Ease of Use: SPSS is easy to use for beginners, as it has a simple graphical user interface especially designed for students and researchers having basic knowledge of statistics. Most of the operations can be performed through the use of menus and dialog boxes, thus minimal programming experience is required for its operation.

Versatility: SPSS can analyse diverse types and formats of data and therefore can be used in various social science research such as experimental research, survey analysis, and observational research.

Comprehensive Statistical Capabilities: SPSS offers almost all advanced statistical procedures that suits the diverse research needs in social sciences. This includes methods for dealing with handling complex survey data, which is common in social science research.

Support for Large Datasets: Social Science research involves big datasets with numerous variables. Due to the ability of SPSS to handle large data sets, it has become the researcher’s preferred data analysis tool.

Integration with Other Software: It can also import and export data using data files from other softwares such as Excel, SAS, Stata and many others, which is viable for researchers who use various tools in their research process.

Using SPSS for Analyzing Survey Data in Social Sciences

Conducting analysis on survey data is one of the common tasks in social sciences research. Surveys are usually conducted to gather information concerning the various areas of life interest, such as the public opinion, consumer behavior to psychological traits and social attitudes. Analyzing survey data with SPSS involves several key steps:

1. Data Import and Preparation: Before analyzing survey data in SPSS, the data is required to be imported into the software. Some of the file formats that can be used includes excel, csv and text files by SPSS. Once the dataset in the raw format is imported, it must be pre-processed before analysis. This involves performing data screening to identify missing values, recoding variables, and creating new variables as needed.

Example: Suppose a student is analyzing survey data on social media usage among college students. The first step would be to import the survey data into SPSS and then check for any missing values or outliers that could affect the analysis.

2. Descriptive Statistics: The next step is descriptive analysis which involves the use of statistical tools to describe the data. This encompasses estimating measures of central tendencies such as mean, median, mode and measures of dispersion such as standard deviation, variance and range. Descriptive statistics are used to understand the data set and to recognize the patterns which may exist.

Example: The student might calculate the average number of hours spent on social media per day by college students and the standard deviation to understand the variability in social media usage.

3. Inferential Statistics: Inferential statistics are used to derive inferences about a population based on a sample. This includes hypothesis testing, in which one is in a position to test theories and assumptions.

Example: If the student wants to test whether there is a significant difference in social media usage between male and female students, they could use a t-test or ANOVA in SPSS.

4. Regression Analysis: Regression analysis is one of the most powerful statistical techniques that is commonly used for studying the relationship between two or more variables. In social sciences, regression is usually applied to explain how various factors affect an outcome. 

Example: The student might use regression analysis to examine how factors like age, gender, and academic performance influence social media usage among college students.

5. Data Visualization: SPSS offers a range of tools for visualizing data, including histograms, bar charts, scatter plots, as well as pie charts. Visualizations are much crucial for communicating the results of an analysis much effectively.

Example: The student could create a bar chart to visually compare the average social media usage between different demographic groups.

6. Interpreting and Reporting Results: The last part of the analysis is the interpretation of the results, and expressing them in a simple and comprehensible language. This includes the presentation of the results to the research questions and the interpretation of the results in the light of the questions. 

Example: The student might interpret the results of their analysis to conclude that female students spend significantly more time on social media than male students and discuss the potential reasons and implications of this finding.

Challenges Faced by Social Science Students in Learning SPSS

SPSS is one of the most powerful tools, and learning to use it effectively can be a challenging work for many students, particularly to those who are new to the field of statistics or data analysis. Some of the common challenges includes:

Understanding the Software Interface: The structure of the SPSS interface is good and easy to use, but due to the availability of multiple sub-menus and steps, the first-time users may get confused.

Choosing the Right Statistical Test: A perennial problem that social science students encounter is the kind of statistical test to apply in a certain analysis because the right test determines the validity of results. 

Interpreting Output: The output generated through SPSS can be confusing, containing numerous tables and figures. Interpreting them and deriving meaningful conclusions might be challenging.

Data Preparation: Data cleaning, transformation and recoding may require careful approach which at times may become challenging.

Application of Results: Connecting the statistical findings to a theory can be challenging, especially for the young statisticians or the students.

SPSS Help for Students: Specific Questions and Research Studies in Social Science

Specific questions that students may expect in their exams include analysing survey data, performing correlation and regression analyses, conducting t-tests and ANOVA, and examining categorical data through chi-square tests. For instance, a student might need to explore the relationship between socioeconomic status and educational attainment, assess the impact of a new policy on public opinion, or evaluate psychological traits using survey responses.

Types of Research Studies Using SPSS

In the social sciences, SPSS is applied both in quantitative and qualitative research projects. Quantitative research include surveys and experiments in which SPSS assists in analysing numerical data to find out whether hypothesis is supported or not, and to find hidden trends and make predictions. SPSS can be used in qualitative analysis to analyse coded data such as open-ended responses in interviews which facilitates pattern recognition. Cross-sectional studies, longitudinal data analysis and experimental study designs are commonly carried out using SPSS in social sciences.

Tips and Tricks for Using SPSS in Social Sciences

Utilize Syntax Commands: SPSS has a point-and-click user interface. But also mastering the syntax commands will save time and make the work reproducible.

Data Cleaning and Preparation: It is crucial always to clean and prepare your data before any analysis can be carried out. It involves examining for cases of missing data, outliers as well as ensuring that the variables are correctly formatted.

Use Descriptive Statistics First: Begin with Descriptive statistics in case you want to have a look at your variables before diving into more complex analyses. This can help identify any anomalies or patterns.

Explore Graphical Options: SPSS help students in providing numerous graphical options for the process of data visualization. Use charts and graphs for better understanding of your data and to effectively communicate your findings.

How to Prioritize Audience Targeting?

Prioritizing audience targeting is essential for the success of any marketing campaign. By focusing on the right audience segments, businesses can maximize the effectiveness of their marketing efforts, increase engagement, and drive better results. In this article, we'll explore strategies for prioritizing audience targeting effectively.

Define Your Ideal Customer Profile: The first step in prioritizing audience targeting is to define your ideal customer profile (ICP). Identify the characteristics, attributes, and behaviors of your ideal customers based on factors such as demographics, psychographics, interests, preferences, and purchasing behavior. Develop detailed buyer personas that represent different segments of your target audience, taking into account their needs, pain points, goals, and motivations.

Segment Your Audience: Once you've defined your ICP, segment your audience into distinct groups based on relevant criteria such as demographics, behavior, interests, location, lifecycle stage, and purchasing history. Segmentation allows you to tailor your marketing messages, offers, and experiences to specific audience segments, increasing relevance and engagement. Prioritize segments that align most closely with your ICP and offer the greatest potential for ROI.

Conduct Market Research: Conduct thorough market research to gain insights into your target audience's needs, preferences, behaviors, and pain points. Use a combination of quantitative and qualitative research methods such as surveys, interviews, focus groups, social listening, and competitor analysis to gather data and insights. Understand where your audience spends their time, what channels they prefer, and what content resonates with them. Use this information to prioritize audience targeting and allocate resources effectively.

Identify High-Value Segments: Identify high-value audience segments that offer the greatest potential for revenue generation and business growth. Look for segments that exhibit characteristics such as high purchasing power, strong affinity for your brand, high lifetime value, and low churn rates. Prioritize targeting these segments in your marketing efforts to maximize ROI and drive long-term profitability.

Align with Business Goals: Prioritize audience targeting that aligns with your business goals and objectives. Whether your goal is to increase brand awareness, generate leads, drive sales, or improve customer retention, focus your targeting efforts on audience segments that are most likely to help you achieve these goals.

What is Quantitative Research in Healthcare

Introduction

In the fast-paced world of healthcare, where every decision can impact patient outcomes and organizational success, reliable data is paramount. Quantitative research plays a pivotal role in providing the insights needed to make informed decisions. From understanding patient demographics to assessing the effectiveness of treatment methods, quantitative research in healthcare serves as a cornerstone for primary market research. In this comprehensive guide, we’ll delve into the intricacies of quantitative research in healthcare and explore its significance in driving evidence-based practices and shaping the future of healthcare delivery.

Understanding Quantitative Research in Healthcare

Quantitative research involves the systematic collection and analysis of numerical data to uncover patterns, trends, and associations within a specific population or sample. In healthcare, this method employs statistical and mathematical techniques to quantify phenomena such as disease prevalence, treatment outcomes, and patient satisfaction levels.

Key Components of Quantitative Research in Healthcare

Challenges that Ph.D. Students Face When Analyzing Quantitative Data

Introduction:

Quantitative Data Analyzing for PhD students often face various challenges while conducting research, including collecting and analyzing data.

Analyzing quantitative data can be a daunting task, especially for students who do not have a strong background in statistics.

Many students struggle with managing large datasets, choosing appropriate statistical methods, and interpreting the results.

In this blog, we will discuss some of the challenges faced by PhD students while analyzing their quantitative data.

Quantitative statistical data analysis’s importance

Regression analysis, multivariate analysis, significance testing, and other statistical methods are frequently used in Statistical data analysis in quantitative research. Expert analysts with strong quantitative skills and broad statistical knowledge are capable of handling these tasks with efficiency. Data can only be inferred statistically once the quantitative data analysis has been completed.

In quantitative data analysis, you must use critical and logical reasoning to transform unstructured data into information that is relevant. It is crucial to use thorough and impartial judgment because the same figure within a dataset may be interpreted in multiple ways. In quantitative research, only experts with the necessary training and expertise should analyze data.

Challenges of Quantitative Research Methods for PhD Students

Dissertation committees frequently criticize the method used to examine a study’s findings harshly. Not to mention how intimidating and challenging statistical data analysis is for PhD candidates in quantitative research.

The four main difficulties that PhD students and researchers have when interpreting quantitative data Analyzing are mentioned below.

1: Hypothesis development

2: Casualty: Cause and Impact

3: Generalizability (External Validity)

4: Reliability (Internal Validity)

1: Hypothesis development

A hypothesis is a statement that a research question has a possible solution. There are two different kinds of hypotheses: the null hypothesis, which states that there has been no effect or change, and the alternative hypothesis (this is usually an experimental hypothesis). We can only obtain evidence that either confirms or contradicts a hypothesis; it can never be proved or refuted. Concepts that need to be measured make up hypotheses. Concepts must be transformed into quantifiable elements and treated as variables.

2: Casualty: Cause and Impact

The process of explaining how things have come to be in their current state involves identifying specific variables in the analysis.

The dependent variable is the variable that is measured to determine the impact of the independent variable.

The independent variable is the variable that the researcher deliberately manipulates to observe its effect on the dependent variable.

The control of the Quantitative Data Analyzing variable is a potential independent variable that is held constant throughout the analysis to eliminate its influence on the dependent variable.

3: Generalizability (External Validity)

This refers to the external validity of a study, which concerns the extent to which the findings can be generalized or applied to other populations or settings beyond the sample studied. It pertains to the degree of extrapolation of results.

4: Reliability (Internal Validity)

In order to validate the research findings, this is concerned with the recurrence of the research. A reliable test must yield consistent results across trials.

The following are some ways that statistical coaches, consultants, or statisticians assist PhD students with statistical data analysis in quantitative research:

consideration of the data

Offering statistics instructions

Creating a plan for analysis

Choosing the study’s software and methodology

Quantitative data analysis implementation

Conclusion:

Analyzing quantitative data is a crucial part of the research process for PhD students. However, it can also be a challenging task that requires a significant amount of time and effort. PhD students need to be aware of the common challenges they may face while analyzing their data, and they should take steps to address these challenges proactively. By seeking help from mentors and peers, using appropriate statistical software, and investing time in learning statistical methods, PhD students can overcome these challenges and produce high-quality research that contributes to their field.

By utilizing statistical support,  PhD students can overcome the difficulties in efficiently assessing their quantitative data with the aid of data analysis in quantitative research. Additionally, these services follow moral standards.

Designs

Study design is a detailed arrangement or procedure for carrying out a study, which makes the researcher to convert the theoretical hypothesis into an operational one. There are two quantitative study designs that have been put forward to study human behavior. The two are grouped as observational and experimental. In observational, the researcher only studies effects of exposure on subjects of study and does not allocate the exposure on the subject of study.

Experimental study of humans is also known as Randomized Controlled Trial (RCT). In this study, the researcher does an experiment on the consequence of exposure by passing on exposure to a selected sample of the study group. Most RCT studies are done to affirm the outcome of observational studies. They are expensive and take much time. This leaves most research questions addressed with one or more observational study designs.

Advantages of Randomized Controlled Trial (RCT)

Randomized controlled trial (RCT) is different from observational studies in that there is an influence on the study factor and randomization of the groups studied. This makes RCT to posses some notable advantages such as the aspect of confounding, internal validity, feasibility/appropriateness and external validity.

Confounding

Jepsen, cites confounding as one of the principal reasons, why associations are deployed in epidemiological studies. Confounding deals with the unique features of the subjects of study. These are patients, who respond to certain exposures differently. The essential aim of study design is to avoid, decrease and asses confounding so that estimation of exposure and outcome is done without bias. It is best done by RCT, since such risks are distributed over the groups investigated.

The two main ways to avoid confounding involve restricting and matching at the design stage and statistical adjustments in the analyses stage using other techniques like stratification or multivariable ways. Such methods demand that variables to be well-known and then evaluated or measured. The randomization process in RCT gives the investigator an opportunity to distribute the known and the unknown potential confounders. They are evenly spread over amidst exposed and unexposed subjects of study. The confounders are, thus, eliminated from associations resulting to no bias on study design done.

Known and unknown confounders are dealt with properly by the RCT. When known confounders are noticed, they are easily dealt with by analyzing the two subjects separately or employing statistical techniques as done by the RCT method.

Jepsen, asserts that unknown confounders are very tricky to deal with. The risk factors of unknown confounders on interventions and outcome are inevitable. This cannot be avoided by observational studies. The best protection not in favor of unknown confounders is the use of randomization. The RCT ensures that the two confounders are well spread between the groups studied.

Internal Validity

Internal validity is the scope to which the end results are true. This may be due to the interventions that are considered influence change in behavior. The balance between the expected benefits and risks that interventions can cause are carefully checked before the RCT is undertaken. RCTs are done expecting that side effects can occur less recurrently than the result. Randomized controlled trial (RCT) is set in such a way that it can detect side effects. RCTs have control experiments that measure the total effects of all interventions that can cause an influence on the results; this procedure is done to check and compare it with the actual treatments.

In RCT, the investigator controls all irrelevant variables and only variables that are expected to influence the study are manipulated. Unwanted exposures are prevented from affecting the outcome. Thus, RCTs provide end results that are free from other unfavorable exposures. Moreover, RCTs provide a strict addition or omission of decisive factors that tend to capitalize on the internal validity of the study. They, thus, show the efficiency of exact therapy in a small patient population.

External Validity

It is the degree to which the outcomes of the RCT experiment can be generalized to a certain population of concentration. These are the group that the done intervention is supposed to assist. RCTs are considered to be highly reliable in determining the effects of treatment. Randomized controlled trials investigators demonstrate that the interventions tested actually work. The procedure is done on a well defined population that acts as a sample to the general public. They then establish an efficacy on a certain limited population doing close monitoring. The outcome can be used reliably as a point of application to the whole population. However, critics have disputed the results citing that the follow-ups done do not amount to clinical standards.

Melnyk & Fineout-Overholt, explain that RCTs can be used further to study strategies of care. This has been seen in studies checking on care for people, who have suffered from coronary syndromes. In fact, it is the randomized controlled trials are very useful in non-therapeutic strategies such as patient education. The trials can be registered on cluster randomization, on units like hospitals, clinics and physicians not concentrating on individual patients.

The research results have registered cases like lowering of blood pressure in chronic uncontrolled hypertension very important and applicable to a big number of patients. This extended to patients even in different settings. When other factors like the setting of the patients are taken into account, the RCT results can be useful in clinical use. Most clinical approaches have criticized the RCT on the basis that it lacks external validity.

Feasibility/Appropriateness

Feasibility of Randomized Controlled Trials (RCT) depends on the exploration done whether the method is possible to be carried out and the expected outcomes are achievable. Before the implementation of the method, it involves enquiry whether the subject of study is in support of it or not. Bhandari, cites that currently the RCT is widely accepted as a method of clinical research, and thus, would be feasible. The method provides empirical evidences, hence, stands a better chance to be appropriate in treatment analysis.

RCT needs small sample cases for analysis of the trial on humans. The small sample cases can easily be provided by the current flow in the clinical set up. Ethical implications that can be identified by study subjects on random allocation are easily dealt with. The method links people in the intervention group with those in control group hence easily feasible.

Some treatments have remarkably special effects that, to a large extent, are not likely to reflect insufficiently controlled biases. Such treatments include blood transfusion for relentless hemorrhagic shock. Such cases do not need research in RCTs, and thus, not feasible or appropriate. In the event when biases are expected to be high, RCTs would be more appropriate than any other method. An example of such case is in the spine surgery trials. RCTs have increasingly enhanced the excellence of spine surgery.

Randomized controlled trial (RCT) has several advantages. More studies are, thus, needed to determine the success of RCT method, though most clinical researchers state that the method is expensive and requires much time. The method plays a significant role to deal with bias in treatment experiments. It distributes risk factors over the groups analyzed.
