Figure 3
A line graph with interpretive coordinates. The x axis ranges from negative two to three and the y axis ranges from negative three to three. The graph includes data points labeled A 1, A 2, A 4, A 5, B 1, B 2, B 4, B 5, C 1, C 4, C 5, age 6, and edu 2. The interpretive coordinates for these points are as follows: A 1 is at negative one point eight three, A 2 is at negative zero point nine six, A 4 is at one point seven two, A 5 is at two point one one, and B 1 is at negative two point five. All values are approximated.Creating an interpretive axis
