Figure 9.16 and Figure 9.16 below graph the change in the incorrect responses from the 1 st test to the 2 nd test for each question. Columns above the 0-line represent an improvement in the number of incorrect responses on the 2 nd test, while columns below the line represent a higher percentage of incorrect responses on the 2 nd test. While there is much divergence between Group A and B, there are some common trends on both sides of the line with respect to certain questions. 371
