CREATE A SCATTER PLOT WITH LINE OF BEST FIT

Here is the scatter plot with the line of best fit. The red line represents the trend of the data based on linear regression.

Would you like more details on the calculation of the best fit line or the meaning of the slope and intercept?

Here are five questions related to this:

1. How is the line of best fit calculated?
2. What does the slope of the best fit line tell us about the data?
3. How can we evaluate the strength of the linear relationship in this scatter plot?
4. How would outliers affect the line of best fit?
5. What are other types of regression lines besides linear?

**Tip:** When interpreting a scatter plot, pay attention to how closely the data points follow the line of best fit to gauge the strength of the relationship.
