A trainer arranged for one of her employee training groups to see the video made from the book Effective Time Management, while all her other training groups read the book without seeing the video. She wanted to know whether videos could be used as effective aids in teaching time management. She tested each group for knowledge and ability to apply the concepts covered after each type of instruction. On all tests, the group that saw the video did better. This group became so interested in Effective Time Management that most individuals in the group chose to read the book, for the first time, entirely on their own initiative.
There was no evidence that the training group that saw the video understood or appreciated Effective Time Management more than the training group that read the book without seeing the video.

a. True
b. Probably True
c. Probably False
d. False
e. Insufficient Data

The correct answer is:

false (d)

Explanation:

From the evidences highlighted in the question, it is clear that the training group that saw the video, understood and appreciated Effective Time Management more than the other group because of the following reasons:

1. The group that watched the video, performed better in the test for knowledge and ability to apply the concepts covered during each type of time management instruction. This shows that they had better understanding of the content of the material in the video than their counterparts that read the book, as it reflected in their better performance, not just in a particular aspect of the test, but in all aspect of the test. So their performance on the test unarguably shows their understanding Effective Time Management.

2. we are also told that some members of the group that watched the video became so interested that they went ahead willingly to read the book. This shows an appreciation for the concept of Effective Time Management, because their interest was aroused in what they saw in the video, and needed to get more, so they opted for the book.
