Learning Paths
Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
Chapter 1
Data and Sampling, Study Design and Experiments
A cook tastes one spoonful and decides about the whole pot. Every survey, poll and medical trial does the same thing with people. This chapter shows how a small sample can speak for a large population, and how it goes wrong when the sample leaves people out. You will choose samples fairly, judge the margin of luck in a poll, and design a study that can tell a cause from a coincidence. Every idea starts from a made-up data set or a simulation, and short Python programs do the counting.

Chapter 5
Correlation and Regression, Tables and Graphs, Study Design and Experiments
Do students who practise more type faster? Is a mountain town cooler than a town by the sea? When we measure two things about each person or place, a scatter plot shows how they move together. This chapter puts a number on that pattern, fits the line that predicts one measurement from the other, and then asks the hard question: does one thing really cause the other? Every idea starts with a made-up data set or a simulation, and short Python programs do the arithmetic. It suits a curious student from Class 9 onwards and any adult who reads graphs in the news.
