TABLE 11-8
An important factor in selecting database software is the time required for a user to learn how to use the system. To evaluate three potential brands (A, B and C) of database software, a company designed a test involving five different employees. To reduce variability due to differences among employees, each of the five employees is trained on each of the three different brands. The amount of time (in hours) needed to learn each of the three different brands is given below:

Below is the Excel output for the randomized block design:

-Referring to Table 11-8, it is appropriate to use the Tukey multiple comparison procedure based on the test result above.

Quizplus · Accepted Answer

The Excel output for randomized block design provides the necessary information to perform the Tukey multiple comparison procedure, which can be used to compare the mean learning times between the three different brands of database software. Therefore, it is appropriate to use the Tukey multiple comparison procedure based on the test result above.
