Question

A mathematics professor created a test that was supposed to be mostly easy except for two challenging problems. The scores of the students are shown in the dot plot below. What is the range of the scores? Do not include the percent sign in your answer.

Answer 1

The range is the difference between the greatest score and the smallest score

The range = Greatest score - smallest score

From the given figure

The smallest score is 70

The greatest score is 93

The range = 93 - 70

The range = 23
