Post Lecture Variation.

1) I collected data from 10 people on 2 variables: a) how many hours of sleep did you get last night; and how energized do you feel from 1 to 5. Here were the responses:

Sleep: 5, 4, 5, 8, 9, 6, 5, 6, 7, 8

Energy: 1, 2, 2, 5, 4, 3, 3, 4, 4, 5

2) Finally, use the 'Variance' and 'Standard Deviation' calculator to enter your data for each of the 2 variables and then tell me what the variance and standard deviation were for each variable and which variable had the wider distribution (larger standard deviation = more width).
