Descriptive Statistics: The Starting Point for Machine Learning - Mean, Median & Mode

Introduction

Did you know that the simple concepts of mean, median, and mode that most students learn in high school or college are part of something much bigger called descriptive statistics? These are not just formulas to memorize for exams, but powerful tools that help us make sense of the world, especially in the realm of machine learning.

If you’ve ever used a weather app, checked the average price of a product, or wondered how your exam scores compare to others, you’ve already encountered descriptive statistics in action. These concepts are the foundation of data analysis, helping us summarize large amounts of information into digestible insights. Whether you're an academic, a data scientist, or just someone working with numbers, understanding these can be incredibly beneficial.

In this blog, we’ll explore mean, median, and mode in simple, relatable terms. You’ll learn why they matter, how they’re used, and how they can even reveal surprising patterns in data. By the end, you’ll see these tools as more than just numbers—they’re a way to understand and tell stories with data.

What Are Descriptive Statistics?

Descriptive statistics are like a summary of a book. Imagine you have a giant dataset filled with numbers. Instead of analyzing every single number individually, descriptive statistics let you condense all that information into a few key takeaways.

Think of descriptive statistics as the answers to these questions:

What is the typical value in the data?

How spread out are the numbers?

Are there any unusual numbers (outliers) in the dataset?

These tools don’t just organize data; they help us make decisions. For example, a sports coach might use descriptive statistics to figure out an average player’s performance, or a teacher might use it to understand how a class performed on a test.

Key Terms

Mean (Average): Represents the typical value of your dataset.

Median (Middle Value): The middle number in a sorted dataset.

Mode (Most Frequent Value): The value that appears most often.

These concepts sound simple, but their real-world applications are profound. Let’s dive deeper into each one.

Mean: The Average Value

The mean is the first thing people think of when summarizing data. It’s the average—a single number that represents the entire dataset.

How to Calculate the Mean

To find the mean:

Add up all the numbers in the dataset.

Divide by the total number of values.

Real-World Example

Imagine your test scores over five exams are: 80, 85, 90, 75, and 95. To calculate the mean:

Add: 80 + 85 + 90 + 75 + 95 = 425

Divide: 425 ÷ 5 = 85

The mean score is 85. This tells you that, on average, you scored 85 on your tests.

Why the Mean Is Useful

The mean helps you understand the “typical” value of a dataset. If you’re a teacher, the mean class score can tell you how well students performed overall. If you’re a business owner, the mean monthly sales can help you track growth.

Limitations of the Mean

The mean can be misleading when there are outliers. Outliers are values that are much higher or lower than the rest of the data.

Example of Outliers: Imagine your test scores are: 80, 85, 90, 75, and 300. The mean becomes:

Add: 80 + 85 + 90 + 75 + 300 = 630

Divide: 630 ÷ 5 = 126

Does 126 represent your performance? Not really! That one outlier (300) skews the mean, making it higher than most of your scores.

Median: The Middle Value

The median is the middle number in a dataset when it’s sorted in order. Unlike the mean, the median isn’t affected by outliers, making it a more accurate representation of data in certain cases.

How to Calculate the Median

Arrange the data in ascending order.

Find the middle value.

If there’s an odd number of values, the median is the middle one.

If there’s an even number of values, the median is the average of the two middle numbers.

Real-World Example

Your daily spending over a week: 30, 40, 45, 50, 100.

Arrange: 30, 40, 45, 50, 100

Median = 45 (middle value)

If an outlier changes your spending to 30, 40, 45, 50, 1000, the median stays at 45. This stability makes the median useful when dealing with skewed data.

Why the Median Is Useful

The median is great for datasets with extreme values or skewed distributions, such as house prices. For example, if most houses in a neighbourhood cost $200,000 but one mansion costs $10 million, the median price gives a clearer picture of the typical home instead of the anomalies. If a family is planning to buy a house and they look at the mean, and it is very high they probably would not want to buy the house that’s where median comes into play. Median gives a clearer picture of the normal prices instead of the outliers.

Mode: The Most Frequent Value

The mode is the value that appears most often in a dataset. It’s especially useful for categorical data or finding trends.

How to Find the Mode

Count how many times each value appears.

The value with the highest count is the mode.

Real-World Example

Survey responses about favourite ice cream flavours: Vanilla, Chocolate, Chocolate, Strawberry, Vanilla, Chocolate.

Vanilla - 2

Strawberry - 1

Chocolate - 3

Mode = Chocolate (appears 3 times).

Why the Mode Is Useful

The mode helps identify popularity or commonality. For instance, in marketing, knowing the most purchased product can guide inventory decisions, like which product do we stock up on.

Summary Each Concept

Mean: Calculate by adding all numbers and dividing by the count. Useful for getting the "average" but can be skewed by outliers.

Median: Found by arranging data and picking the middle value. Excellent for skewed data because it's not influenced by outliers.

Mode: Identified by finding the most frequent data point. Great for understanding commonality or popularity in categorical data.

Conclusion

Descriptive statistics aren’t just numbers; they’re tools that help us make sense of data and the world around us. By understanding mean, median, mode, variance, and standard deviation, you can:

Summarize data quickly.

Identify patterns and outliers.

Prepare data for deeper analysis in machine learning.

So, the next time you see a dataset, don’t just glance over it—ask yourself: What story is this data telling? With descriptive statistics, you have the power to find out.

Insights with Descriptive Statistics

Through mean, median, and mode, descriptive statistics allow us to quickly summarize data, identify patterns, and prepare for more complex analyses. These concepts aren't just tools for calculation; they offer us ways to view and interpret the vast amounts of data that inform decisions in fields ranging from education to economics.

You might be wondering why I've mentioned Variance and Standard Deviation towards the end. This is because these concepts are fundamental in descriptive statistics and are vital for machine learning and data analysis. Variance and Standard Deviation provide us with insights into the spread and variability of data, aspects that mean, median, and mode cannot capture alone.

Hi,

For beginners in data science, several concepts can be challenging due to their complexity and depth. 

Here are some of the most common challenging concepts in statistics and machine learning:

Statistics:

Probability Distributions: Understanding different probability distributions (e.g., normal, binomial, Poisson) and their properties can be difficult. Knowing when and how to apply each distribution requires a deep understanding of their characteristics and applications.

Hypothesis Testing: Hypothesis testing involves formulating null and alternative hypotheses, selecting appropriate tests (e.g., t-tests, chi-square tests), and interpreting p-values. The concepts of statistical significance and Type I/Type II errors can be complex and require careful consideration.

Confidence Intervals: Calculating and interpreting confidence intervals for estimates involves understanding the trade-offs between precision and reliability. Beginners often struggle with the concept of confidence intervals and their implications for statistical inference.

Regression Analysis: Multiple regression analysis, including understanding coefficients, multicollinearity, and model assumptions, can be challenging. Interpreting regression results and diagnosing issues such as heteroscedasticity and autocorrelation require a solid grasp of statistical principles.

Machine Learning:

Bias-Variance Tradeoff: Balancing bias and variance to achieve a model that generalizes well to new data can be challenging. Understanding overfitting and underfitting, and how to use techniques like cross-validation to address these issues, requires careful analysis.

Feature Selection and Engineering: Selecting the most relevant features and engineering new ones can significantly impact model performance. Beginners often find it challenging to determine which features are important and how to transform raw data into useful features.

Algorithm Selection and Tuning: Choosing the appropriate machine learning algorithm for a given problem and tuning its hyperparameters can be complex. Each algorithm has its own strengths, limitations, and parameters that need to be optimized.

Model Evaluation Metrics: Understanding and selecting the right evaluation metrics (e.g., accuracy, precision, recall, F1 score) for different types of models and problems can be challenging.

Advanced Topics:

Deep Learning: Concepts such as neural networks, activation functions, backpropagation, and hyperparameter tuning in deep learning can be intricate. Understanding how deep learning models work and how to optimize them requires a solid foundation in both theoretical and practical aspects.

Dimensionality Reduction: Techniques like Principal Component Analysis (PCA) and t-Distributed Stochastic Neighbor Embedding (t-SNE) for reducing the number of features while retaining essential information can be difficult to grasp and apply effectively.

To overcome these challenges, beginners should focus on building a strong foundation in fundamental concepts through practical exercises, online courses, and hands-on projects. Seeking clarification from mentors or peers and engaging in data science communities can also provide valuable support and insights.

Kickstart Your Tech Career: Why Internships Are More Important Than Ever

In the rapidly changing digital economy we live in today, a degree no longer suffices. What truly makes you stand out is practical experience—and that's where internships fit in.

If you are a computer science or IT bachelor's or master's degree holder, applying for a Java internship for freshers can prove to be one of the best decisions you ever took. Java remains a basis of enterprise software, and hence it is extremely important to study Java for those who are interested in working on backend development, application security, or web systems with scalability. Internships provide freshers with hands-on experience in writing optimized code, debugging, version control, and project collaboration.

On the opposite end, the world of technology is also eager for developers who excel at everything. This is why an full stack web development internship is a first preference for future professionals. With these internships, you get exposed to frontend and backend technologies—HTML, CSS, JavaScript, React, Node.js, Express, MongoDB, etc.—and you become a jack-of-all-trades of the world.

But above all, it is not that these internships simply teach you how to code, but how they teach you how to work, manage teams, deadlines, and deployable applications that solve real problems.

From product companies to tech startups or freelance work, the hands-on experience you learn through a concerted internship can define your career path. Theory is fine to learn, but experience is what gets you ready for a job.

AI enables shift from enablement to strategic leadership

New Post has been published on https://thedigitalinsider.com/ai-enables-shift-from-enablement-to-strategic-leadership/

AI enables shift from enablement to strategic leadership

CIOs and business leaders know they’re sitting on a goldmine of business data. And while traditional tools such as business intelligence platforms and statistical analysis software can effectively surface insights from the collated data resources, doing so quickly, in real-time and at scale remains an unsolved challenge.

Enterprise AI, when deployed responsibly and at scale, can turn these bottlenecks into opportunities. Acting quickly on data, even ‘live’ (during a customer interaction, for example), is one of the technology’s abilities, as is scalability: AI can process large amounts of information from disparate sources almost as easily as it can summarize a one-page spreadsheet.

But deploying an AI solution in the modern enterprise isn’t simple. It takes structure, trust and the right talent. Along with the practical implementation challenges, using AI brings its own challenges, such as data governance, the need to impose guardrails on AI responses and training data, and persistent staffing issues.

We met with Rani Radhakrishnan, PwC Principal, Technology Managed Services – AI, Data Analytics and Insights, to talk candidly about what’s working — and what’s holding back CIOs in their AI journey. We spoke ahead of her speaking engagement at TechEx AI & Big Data Expo North America, June 4 and 5, at the Santa Clara Convention Center.

Rani is especially attuned to some of the governance, data privacy and sovereignty issues that face enterprises, having spent many years in her career working with numerous clients in the health sector — an area where issues like privacy, data oversight and above all data accuracy are make-or-break aspects of technology deployments.

“It’s not enough to just have a prompt engineer or a Python developer. … You still need the human in the loop to curate the right training data sets, review and address any bias in the outputs.” —Rani Radhakrishnan, PwC

From support to strategy: shifting expectations for AI

Rani said that there’s a growing enthusiasm from PwC’s clients for AI-powered managed services that can provide both business insights in every sector, and for the technology to be used more proactively, in so-called agentic roles where agents can independently act on data and user input; where autonomous AI agents can take action based on interactions with humans, access to data resources and automation.

For example, PwC’s agent OS is a modular AI platform that connects systems and scales intelligent agents into workflows, many times faster than traditional computing methods. It’s an example of how PwC responds to the demand for AI from its clients, many of whom see the potential of this new technology, but lack the in-house expertise and staff to act on their needs.

Depending on the sector of the organization, the interest in AI can come from many different places in the business. Proactive monitoring of physical or digital systems; predictive maintenance in manufacturing or engineering; or cost efficiencies won by automation in complex, customer-facing environments, are just a few examples.

But regardless of where AI can bring value, most companies don’t yet have in-house the range of skills and people necessary for effective AI deployment — or at least, deployments that achieve ROI and don’t come with significant risk.

“It’s not enough to just have a prompt engineer or a Python developer,” Rani said. “You’ve got to put all of these together in a very structured manner, and you still need the human in the loop to curate the right training data sets, review and address any bias in the outputs.”

Cleaning house: the data challenge behind AI

Rani says that effective AI implementations need a mix of technical skills — data engineering, data science, prompt engineering — in combination with an organization’s domain expertise. Internal domain expertise can define the right outcomes, and technical staff can cover the responsible AI practices, like data collation and governance, and confirm that AI systems work responsibly and within company guidelines.

“In order to get the most value out of AI, an organization has to get the underlying data right,” she said. “I don’t know of a single company that says its data is in great shape … you’ve got to get it into the right structure and normalize it properly so you can query, analyze, and annotate it and identify emerging trends.”

Part of the work enterprises have to put in for effective AI use is the observation for and correction of bias — in both output of AI systems and in the analysis of potential bias inherent in training and operational data.

It’s important that as part of the underlying architecture of AI systems, teams apply stringent data sanitization, normalization, and data annotation processes. The latter requires “a lot of human effort,” Rani said, and the skilled personnel required are among the new breed of data professionals that are beginning to emerge.

If data and personnel challenges can be overcome, then the feedback loop makes the possible outcomes from generative AI really valuable, Rani said. “Now you have an opportunity with AI prompts to go back and refine the answer that you get. And that’s what makes it so unique and so valuable because now you’re training the model to answer the questions the way you want them answered.”

For CIOs, the shift isn’t just about tech enablement. It’s about integrating AI into enterprise architecture, aligning with business strategy, and managing the governance risks that come with scale. CIOs are becoming AI stewards — architecting not just systems, but trust and transformation.

Conclusion

It’s only been a few years since AI emerged from its roots in academic computer science research, so it’s understandable that today’s enterprise organizations are, to a certain extent, feeling their way towards realizing AI’s potential.

But a new playbook is emerging — one that helps CIOs access the value held in their data reserves, in business strategy, operational improvement, customer-facing experiences and a dozen more areas of the business.

As a company that’s steeped in experience with clients large and small from all over the world, PwC is one of the leading choices that decision-makers turn to, to begin or rationalize and direct their existing AI journeys.

Explore how PwC is helping CIOs embed AI into core operations, and see Rani’s latest insights at the June TechEx AI & Big Data Expo North America.

Is it possible to transition to a data scientist from a non-tech background at the age of 28?

Hi,

You can certainly shift to become a data scientist from a nontechnical background at 28. As a matter of fact, very many do. Most data scientists have actually shifted to this field from different academic and professional backgrounds, with some of them having changed careers even in their midlife years. 

Build a Strong Foundation:

Devour some of the core knowledge about statistics, programming, and data analysis. Online classes, bootcamps—those are good and many, many convenient resources. Give it a whirl with Coursera and Lejhro for specific courses related to data science, machine learning and programming languages like Python and R.
