One of the most common things in statistics is to describe the linear relationship between two variables by fitting a best-fit line to the scatterplot of those variables. The method for finding the best-fit line is called simple linear regression and is the topic of this module.
After completing this module, you should be able to ...
- Fit a regression line in R.
- Visualize the regression line in R.
- Make predictions using the regression line in R
