Answer

Explanation:

Step1: Calculate range for first data - set

Range = Max - Min. For the data set of days students buy school lunch (0, 3, 5, 5, 2, 3, 1, 0, 5, 5, 2, 1), Max = 5, Min = 0. Range = 5 - 0 = 5.

Step2: Calculate range for second data - set

For the data set of hours of sleep (8, 7, 8, 9, 7, 8, 8, 8, 10, 8, 9, 8), Max = 10, Min = 7. Range = 10 - 7 = 3.

Step3: Calculate range for third data - set

For the data set of minutes playing video - games (30, 60, 60, 0, 20, 75, 30, 15, 0, 30, 0, 25), Max = 75, Min = 0. Range = 75 - 0 = 75.

Step4: Compare ranges

We have ranges 5, 3, and 75. Since 75>5>3.

Answer:

The data set of how many minutes students spend playing video games each day has the most variability.
