strongly agreed that they used the tutorial to answer the question and that it was effective in
doing so. Having not attended the lecture, they had no other reference to answer the
questions and were more reliant upon the tutorial to provide information. This Group ended
up with the best test results, indicating a clear effectiveness to the printed tutorial.
9.1.4.3 Comparison of Groups A and B
There is a remarkable similarity between the results of Group A and B (base group). Figure
9.10 shows that the deviation between groups in the 1 st test was within 3% for the “right” and
“don’t know” responses, with parity for the “wrong” response. This uniformity is somewhat
surprising, but explainable by the similar conditions under which the groups were
administered the first test. The 2 nd tests however, were administered under quite different
conditions between the groups, so the comparative results of this test are considerably more
surprising; the correct responses were on par, while the incorrect and “don’t know”
responses were within one percent between Groups A and B.
