Students re-engage in their work on linear relationships as they analyze scatter plots for possible linear associations. They recall positive and negative slopes in the coordinate plane and use this understanding to describe behaviors of one variable in relation to the other.

Modified by The Match Foundation, Inc.Medhavi suspects that there is a relationship between the number of text messages high school students send and their academic achievement. To explore this, she asks each student in a random sample of 52 students from her school how many text messages he or she sent yesterday and what his or her grade point average (GPA) was during the most recent marking period. The data are summarized in the scatter plot of number of text messages sent versus GPA shown below.
