Think STATS
Think Stats is a hands-on introduction to statistics and exploratory data analysis that teaches through code rather than proofs. Allen B. Downey works through real datasets in Python, building up distributions, probability, hypothesis testing, and regression as things you compute and plot instead of memorize. It reads like a working notebook: short chapters, exercises, and code you can run yourself. Readers comfortable with a little programming will get the most from it. It sits alongside Downey's other 'Think' books, Think Python and Think Bayes, and shares their practical, example-first spirit.
