Correlation and regression

What you'll learn

1. 1

   Imagine you're tracking how many hours you study 📚 and your test score 🎯. When one goes up, does the other usually go up too? That's a correlation!

2. 2

   Here's a scatter plot showing hours studied vs test scores. Each dot is one student.

3. 3

   What do we call it when one thing goes up and the other goes up too?

4. 4

   Let's find the line of best fit for these points.

5. 5

   Drag the line to fit the scatter plot — try to balance the points above and below.

6. 6

   If hours studied goes up and test score goes down, what kind of correlation is that?

7. 7

   Match the scatter plot to the correlation type.
