Does meditation cure insomnia? Researchers randomly divided 400 people into two equal- sized groups. One group meditated daily for 30 minutes, the other group attended a 2-hour information session on insomnia. At the beginning of the study, the average difference between the number of minutes slept between the two groups was about 0. After the study, the average difference was about 32 minutes, and the meditation group had a higher average number of minutes slept. To test whether an average difference of 32 minutes could be attributed to chance, a statistics student decided to conduct a randomization test. She wrote the number of minutes slept by each subject in the study on an index card. She shuffled the cards together very well, and then dealt them into two equal-sized groups. Which of the following best describes the outcome?

As per the question, at the beginning of the study the average difference was seen as 0 minutes, but after the experiment the average difference was of 32 minutes.

To Cross examine the study result, the researcher recorded the number of minutes slept on an index card and shuffled the cards into two equal parts. There can be three outcomes of this test, these are:

The average difference will be about 0 minutes.
The average difference will be more than 32 minutes.
The average difference will be about 32 minutes.

There is three outcomes because of shuffling of the cards.
