Python Statistics

Statistics is the thinking behind every chart and model, and these 4 tutorials keep it practical. You learn descriptive statistics, probability distributions, hypothesis testing with t-tests and chi-square, and correlation and regression, all in working Python code. No formula dumps, just intuition backed by examples you can run.

Statistics: Probability Distributions, Normal and Binomial

Avatar for RahulPython + AI/ML Tutorial
Flip a coin and both outcomes are equally likely. Measure 10,000 heights and most bunch near the middle. Count website visitors per hour and you get bursts around a steady average. Python probability distributions put names, formulas, and SciPy code on those patterns, and this post works through the five you will actually meet: normal, binomial, Poisson, uniform, and exponential. “Probability is the language of uncertainty.” Dennis Lindley, statistician Last Updated: July 2026 | Tested on: Python 3.14.6, SciPy 1.18.0 ...

Statistics: Hypothesis Testing with t-test and chi-square

Avatar for RahulPython + AI/ML Tutorial
Perform hypothesis testing in Python: null and alternative hypotheses, p-values, t-tests (one-sample, independent, paired), chi-square, and a decision tree for choosing the right test (including where ANOVA fits) in this hypothesis testing python guide. “To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination.” Ronald Fisher, Statistical Methods Last Updated: July 2026 | Tested on: Python 3.14.6, SciPy 1.18.0 | Difficulty: Advanced | Reading Time: 16 minutes Your ...

Statistics: Correlation & Regression Analysis

Avatar for RahulPython + AI/ML Tutorial
Python correlation and regression measure how two variables move together: Pearson and Spearman correlation, correlation matrices, simple linear regression from scratch and with SciPy, R-squared, and residual analysis, every number run on real code. “Correlation does not imply causation, but it does waggle its eyebrows suggestively.” Randall Munroe, xkcd Correlation answers one simple question: when one number goes up, does the other one tend to go up too, go down, or just do its own thing? Regression goes one step ... Read More
