Course 4 · Module 2
Statistics
This module covers the branch of mathematics that reasons from data back to the world. You'll see how a 17th-century study of London's death records began the field, how a sample of a thousand people can tell you about millions, and why every estimate comes with a margin of error. You'll then judge the evidence behind medical trials, psychological tests, and published research, including the debate over whether much of it holds up.
Module objectives
- Explain how a sample is used to estimate a population value and why every estimate carries uncertainty.
- Evaluate the design and measurement behind a statistical claim, and describe the current debate over p-values and replication.
