Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

Match correlation coefficients to scatterplots to build a deeper intuition behind correlation coefficients. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice plotting points to construct a scatter plot. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

A good scatter plot has the independent variable on the x-axis and the dependent variable on the y-axis. Also, the scale of both axes should be reasonable, making the data as easy to read as possible. In these practice problems, we...
