We interpret scatter plots, investigate the relationship between variables, interpret the slope of a trend line, and make predictions based on the trend line's slope and intercept. video https://cdn.kastatic.org/ka_thumbnails_cache/99fc0bd7-0b3e-4634-94dc-23d54366b16a_1280_720_base.png Interpreting slope of regression line We look at an example scatter plot showing the relationship between hours studying and test scores.
