A researcher explores the relationship between self-control (as a self-reported trait) and impulsive buying among 30 unemployed adults between the ages of 25 and 40. Scores on the self-control scale can range from 20 to 100, with higher scores suggesting more of this trait. Impulsive buying was assessed with 5 items, and scores can range from 5 to 25, with higher scores reflecting more impulsive buying behavior. The correlation between the variables is -.46. The researcher also computes the linear regression predicting impulsive buying from self-control and finds that Y'=-.25X + 20
