Kaylee wants to test her hypothesis that she performs better on tests after getting more sleep. in which way will she best be able to do this?

She should establish the categories she would test and then record the scores that she obtain in relation with the hours she sleeps.

Explanation:

Kaylee wants to test her hypotehsis that she performed better on tests after getting more sleep. She has two variables: the number of hours she sleeps and the scores she obtains.

To test her hypothesis, she should:

1) Establish categories  for the number of hours she sleeps (for example 5-6 hours of sleep, 7-8 hours of sleep and 9-10 hours of sleep).

2)Recor the scores she obtains in relation to the number of hours she sleeps. For example, when she sleeps 5-6 hours she obtains 6,7,5,7,6; when she sleeps 7-8 hours she obtains 7,8,7,7,8; and finally when she sleeps 9-10 hours she obtains 8,9,9,9,10.

3) She have to analyze data and look for a correlation between both variables.
