Scatter Plots and Lines of Fit

Overview

Goal. Describe the association in a scatter plot, write a line of fit from two points on the line, interpret its slope and intercept in context, and use it to predict values.

Line of fit (definition). A line drawn through a scatter plot that follows the trend of the data, with points balanced above and below it. It models the relationship between the two variables and is used to make predictions.
