Answer:

A

Step-by-step explanation:

Eighth grade students have more variation in the amount of time spent online last night.

What is the correct option?

A box plot is used to study the distribution of a set of numbers. The numbers are placed in group of 25%.

Range can be used to determine the variation of the data set. The range can be determined using the ends of the whiskers of the box plots.

Range = maximum number - minimum number

8th graders = 120 - 0 = 120

7th graders = 100 - 0 = 100
