What would you include in a mini-report that fully describes all aspects of a linear association? Make as detailed a list as you can.

Fully describe all aspects of the linear association in context. Include appropriate graphs.

Use your calculator to make a scatterplot.

Complete and draw LSRL.

Verify linearity with a residual plot.

Describe the form, direction (including the slope and *y*-intercept in context),

strength (including an interpretation or *r* and *R*^{2}), and possible outliers.

Draw upper and lower bounds for the model used for prediction.
