Foundations of Experimentation
A practical survival guide for building experiments that will not lie to you. You do not need to memorize formulas or run your own analysis. You just need to understand why experiments work, what can break them, and how to tell good data from garbage data.

Getting Started
Orient yourself to the course and the statistical mindset that separates trustworthy experiments from guesswork.
Why Experiments Work
Understand what separates proof from correlation: study types, randomized controlled trials, and why A/B tests bring scientific rigor to product and growth decisions.
Sampling and Statistics
The statistical core: how sampling and assignment work, why variance and the central limit theorem matter, and how power, error rates, sample size, and MDE decide whether a test can succeed.
Designing and Reading Experiments
Put the statistics to work: size experiments with calculators, interpret p-values and confidence intervals, watch a simulation, and know when to stop and how to spot a broken test.
