Figure 9.13 Comparison of “don’t know” responses between Groups A and B.
Despite the parity of overall results between Groups A and B, differences emerge as the
results are analyzed at a higher level of detail. For example, a renewed focus on the
incorrect responses shows less consistency between the Groups. Figure 9.14 compares the
percentage of incorrect answers on the 2 nd test between Groups A and B. Only four
questions were answered incorrectly by both groups over 30% of the time; 4, 10, 11 and 21.
These questions are discussed following (question 11 is included in the section on the Glass
System category below).
