Statistics

Statistics is a core part of Data Science. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding statistics well means you can read other people's Data Science code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

What statistics means in the context of Data Science
A minimal example you can run or read in the playground on the right
A common mistake to avoid when working with statistics

Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for statistics.
