Statistics with Python – 100 Solved Exercises for Data Analysis

In the evolving world of data analysis, one skill remains timeless and fundamental: statistics. No matter how advanced your machine learning models or data pipelines are, a core understanding of statistics empowers you to make sound, interpretable decisions with data. One book that takes a unique approach to this subject is "Statistics with Python. 100 Solved Exercises for Data Analysis" by Your Data Teacher.

Unlike dense academic textbooks or broad theoretical overviews, this book positions itself as a hands-on guide, ideal for readers who want to build statistical intuition by applying concepts directly in Python.

Purpose and Audience

The book is tailored for:

Beginners in data science or analytics

Students studying statistics who want practical coding experience

Python programmers wanting to develop statistical understanding

Professionals seeking to upgrade from Excel or business intelligence tools to code-based analysis

Its objective is clear: make statistical thinking accessible and actionable through practical Python exercises.

It does not attempt to be a comprehensive treatise on statistics. Instead, it serves as a practice workbook, offering 100 problems with structured solutions that demonstrate how to use Python’s statistical and data-handling libraries effectively.

Book Structure and Flow

The book is logically structured and progresses from foundational to more applied topics. Here's a breakdown of its main sections:

1. Descriptive Statistics

This section lays the groundwork by focusing on measures that summarize data. Readers are introduced to core metrics like central tendency, variability, and data distribution characteristics. The solutions show how to compute and interpret these metrics using Python’s numerical libraries.

2. Probability and Distributions

This portion delves into the probabilistic foundations of data analysis. It covers probability distributions — both discrete and continuous — and explains concepts such as randomness, density functions, and the shape and behavior of data under various theoretical models.

3. Inferential Statistics

Here, the focus shifts from describing data to making judgments and predictions. Readers learn how to estimate population parameters, conduct hypothesis testing, and interpret significance levels. The book uses real-world logic to introduce tests such as t-tests and chi-square tests, helping readers understand when and why these tools are applied.

4. Correlation and Regression

This section is dedicated to exploring relationships between variables. By walking through correlation coefficients and linear regression modeling, it helps readers grasp the difference between correlation and causation and learn how to model simple predictive relationships.

5. Practical Data Analysis and Interpretation

Toward the end of the book, the exercises become more integrated and context-driven. This final section simulates the kind of challenges data analysts face in real projects — synthesizing techniques, interpreting results in business or research contexts, and visualizing insights.

 Teaching Approach

The strength of this book lies in its pedagogical approach:

Problem-Solution Format: Each exercise starts with a clear problem statement, followed by a step-by-step walkthrough of the solution. This scaffolding allows readers to understand both how and why a method works.

Progressive Complexity: Exercises are arranged to build on previous concepts. This makes the book suitable for sequential study, ensuring a solid foundation before moving to complex analysis.

Interpretation Over Memorization: While computation is central, the book repeatedly emphasizes understanding the meaning of results, not just the mechanics of calculation.

Library Familiarity: Readers gain experience using key Python libraries such as pandas, numpy, scipy, and visualization tools like matplotlib and seaborn. This also prepares them for working with real data in more complex environments.

Strengths of the Book

Practical Focus: Rather than overwhelming readers with abstract concepts, the book shows how statistics are used in actual data analysis workflows.

Compact and Accessible: The writing is concise and approachable. It's free of unnecessary jargon, making it friendly for self-learners and non-technical professionals.

Real Python Usage: Solutions are grounded in actual Python code, reinforcing programming skills while teaching statistics. It’s a dual-purpose resource that strengthens both areas.

Excellent for Reinforcement: The sheer volume of exercises makes this a powerful tool for practice. It's ideal for students preparing for exams or interviews where applied statistics are tested

Use Cases and Practical Value

This book is a great resource for:

Building confidence in applying statistical techniques

Practicing Python coding in a data analysis context

Preparing for technical interviews or data science bootcamps

Creating a structured self-study plan

Enhancing an academic course with additional problem-solving

It’s especially valuable for those who have taken an online course in statistics or Python and now want to solidify their skills through application.
