Question

Maria is recording the percentages she earned on each quiz in her math class. Here are her results for the last 7 quizzes.59, 61, 83, 67, 81, 80, 81Find the range of the data set.

Answer 1

Given:

The percentages of each quiz are as follows:

59, 61, 83, 67, 81, 80, 81

To find the range of the data set, we will arrange the data from the least to the greatest.

So, the data set after arrangement will be:

59, 61, 67, 80, 81, 81, 83

So, the maximum percentage = 83

and the minimum percentage = 59

The range = maximum - minimum = 83 - 59 = 24

so, the answer will be Range = 24
