3. RESULTS 3.1 Completion Time Figure 1 shows that the subjects performed their tasks faster on average with the full context menu than with the limited context menu. The t-test was computed on the results and it was determined that there was no significant difference between the completion times of both types of frames. (T-stat = -0.71 < 0.05) Table 1. Completion Time: (S.D. in parenthesis)
Figure 1. Completion Time  3.2 Accuracy of Information Retrieval Figure 2 shows that the full Context menu had a higher number of errors than the limited context menu. The t-test was computed on the results and the Number of errors was determined to be significantly different for both types of frames. (T-stat = 0.68 > 0.05) Table 2. Accuracy of Information Retrieval: (S.D. in parenthesis)
Figure 2. Accuracy of Information Retrieval 3.3 Subjective Ranking Figure 3 shows that, on average, the subjects preferred the full context menu structure to the limited context menu structure. The t-test was computed on the results and it was determined that the subjective ratings for the full context menu was significantly different from the subjective ratings for the limited context menu. (T-stat = 1.78 > 0.05) Table 3. Subjective Ranking: (S.D. in parenthesis)
