Why Statistics Matters in Data Science

This lesson explains why statistics is a core skill in data science, not just a math prerequisite. You will learn how statistical thinking helps you separate signal from noise, make decisions under uncertainty, and avoid common mistakes when interpreting data.

By the end of the lesson, you should be able to describe the role of statistics in analysis, explain why samples are used instead of full populations, and recognize how uncertainty affects conclusions in real-world data work.
