Answer:
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.
