Quizplus · Accepted Answer

The output from the randomized block design shows that there are significant differences in the mean times required to learn the three different database software brands. Since the design involves a randomized complete block design, it is appropriate to use the Tukey multiple comparison procedure to identify which brands are significantly different from each other.
