# Correlation coefficient and line of best fit

- Topic:
- Correlation

1. Graph these points on graph paper.
Draw the line of best fit. Find its equation.
Check the box to see if your line agrees with the computer.
2. You can move the points to try a new example.
3. Move one or more points to see what effect it has on the line of best fit.
(Does the line of best fit have to go through any of the points?)
4. Can you have a line of best fit if the correlation coefficient is zero? Move the points to see.
5. Click the reset icon to return to the first set-up.
