🧠 Top 10 Statistics Formulas Every Data Analyst Should Know

Why These Formulas Matter Statistics is the foundation of data science, analytics, research, and decision-making. These formulas help you:

Understand and summarize data

Identify patterns and trends

Test hypotheses and assumptions

Communicate insights clearly

Let’s explore the top 10 formulas you must know.

1. Mean (Average)

Formula: Mean = (x₁ + x₂ + ... + xₙ) / n

Explanation: The central value of a dataset — helps in understanding the overall trend.

2. Standard Deviation (σ)

Formula: σ = √[Σ(xᵢ - μ)² / n]

Explanation: Shows how spread out the numbers are from the mean — key for variability.

3. Variance (σ²)

Formula: σ² = Σ(xᵢ - μ)² / n

Explanation: The square of standard deviation — useful in model evaluation and statistics.

4. Probability (P)

Formula: P(A) = Number of favorable outcomes / Total outcomes

Explanation: Core of inferential statistics — used in predictions and risk assessment.

5. Bayes’ Theorem

Formula: P(A|B) = [P(B|A) × P(A)] / P(B)

Explanation: Calculates conditional probability — widely used in ML and diagnostics.

6. Z-Score

Formula: z = (x - μ) / σ

Explanation: Tells how many standard deviations a point is from the mean — useful for anomaly detection.

7. Confidence Interval (CI)

Formula: CI = x̄ ± Z*(σ/√n)

Explanation: Gives a range that likely contains the true population mean — essential for surveys.

8. p-value

Formula: Depends on test statistic (e.g., t or z distribution)

Explanation: Tells the probability of observing results under the null hypothesis — core for significance testing.

9. t-Test Statistic

Formula: t = (x̄₁ - x̄₂) / √[(s₁²/n₁) + (s₂²/n₂)]

Explanation: Used to compare means between two groups — key in A/B testing.

10. Pearson’s Correlation Coefficient (r)

Formula: r = Σ[(x - x̄)(y - ȳ)] / √[Σ(x - x̄)² × Σ(y - ȳ)²]

Explanation: Measures the strength and direction of a linear relationship between two variables.

Final Thoughts These formulas are the backbone of statistical reasoning and data analysis. Whether you’re exploring customer trends, testing experiments, or interpreting research — they’re must-haves.

Exploring the Association Between Socioeconomic Status and Medical Treatment Seeking

1. Data Set Selection

I have chosen the National Health and Nutrition Examination Survey (NHANES) dataset for my analysis. NHANES is a comprehensive dataset that collects health, nutrition, and socio-economic data from a representative sample of the U.S. population. I am particularly interested in exploring the relationship between socioeconomic status (SES) and medical treatment seeking. The NHANES dataset includes a wide range of variables related to medical treatment, socio-economic factors, and health outcomes, making it ideal for studying this association.

2. Research Question and Hypothesis

The research question I am interested in investigating is:

" Is socioeconomic status associated with the likelihood of seeking medical treatment for health issues? "

I hypothesize that individuals with lower socioeconomic status will be less likely to seek medical treatment compared to those with higher socioeconomic status. This could be due to factors such as financial constraints, lack of health insurance, or lower access to healthcare resources.

3. Codebook Preparation

To explore this question, I have prepared a personal codebook based on the NHANES dataset. The variables I have selected are related to socioeconomic status (e.g., income, education level, and employment status) and medical treatment seeking behaviors (e.g., doctor visits, medication use, and health insurance coverage). Below is a brief outline of the variables included in my codebook:

Socioeconomic Status Variables:

Income Level (INDFMPIR): The ratio of family income to the federal poverty level.

Education Level (DMDEDUC2): Highest level of education completed by the participant.

Employment Status (OHXSTAT): Employment status, including categories like employed, unemployed, and not in the labor force.

Medical Treatment Seeking Variables:

Doctor Visits (HCVDOCT): Whether the individual has visited a doctor in the past year.

Medication Use (RXDUSE): Whether the individual used prescription medications in the past month.

Health Insurance Coverage (HIQ020): Whether the individual has health insurance coverage.

These variables will allow me to analyze the relationship between SES and medical treatment seeking.

4. Secondary Topic of Interest

A secondary topic that I would like to explore in relation to my primary topic is the relationship between health insurance coverage and medical treatment seeking. Given that insurance is a key factor in an individual's ability to access medical care, I hypothesize that those with health insurance are more likely to seek medical treatment, regardless of their socioeconomic status.

5. Additional Codebook Variables for Secondary Topic:

Health Insurance Coverage (HIQ020): Included in the primary codebook, but will be emphasized here as a key factor.

Doctor Visits (HCVDOCT): Used again to measure the seeking of medical care, particularly among those with and without insurance.

6. Literature Review

To inform my hypothesis, I conducted a literature review using Google Scholar. The search terms I used included “socioeconomic status and medical treatment seeking,” “health insurance and medical care utilization,” and “income and doctor visits.” Here is a summary of the findings:

Socioeconomic Status and Medical Treatment Seeking:

Several studies have found that individuals with lower SES are less likely to seek medical care, often due to financial barriers, lack of insurance, and limited access to healthcare facilities (Schneider et al., 2019).

Lower-income individuals are more likely to delay or forgo medical treatment, which can lead to worse health outcomes over time (Baker et al., 2020).

Health Insurance and Medical Treatment Seeking:

Health insurance has been shown to significantly increase the likelihood of seeking medical care. People without insurance are less likely to have regular doctor visits and are more likely to delay necessary treatment (Williams et al., 2021).

Studies indicate that individuals with health insurance are more likely to receive preventive care and early intervention, reducing the burden of chronic conditions (Chen & Mullahy, 2019).

Based on these findings, I believe that SES, especially income, plays a significant role in whether individuals seek medical treatment. However, health insurance may serve as a key mediator in this relationship.

7. Hypothesis

Based on my literature review, I hypothesize that individuals with lower SES, particularly those with lower income and education levels, will be less likely to seek medical treatment. However, this relationship will be moderated by the presence of health insurance coverage, where individuals with health insurance, regardless of their SES, will be more likely to seek medical care.

8. Conclusion

In this blog post, I have chosen the NHANES dataset to explore the association between socioeconomic status and medical treatment seeking. I have outlined my research question, hypothesis, and the variables I have selected for my personal codebook. I also identified a secondary topic regarding health insurance coverage and its potential moderating effect on the relationship between SES and medical treatment seeking. My literature review provides further context for understanding the dynamics at play, and I look forward to analyzing the data to test my hypothesis.
