Question

What is the range of this data set? 12.5, 10.1, 11.4, 17.3, 17.9, 12.1, 14.1, 14.4, 20.4, 19.1, 12.4, 18.9

Answer 1

10.3

Explanation:

Given set of values

• 12.5, 10.1, 11.4, 17.3, 17.9, 12.1, 14.1, 14.4, 20.4, 19.1, 12.4, 18.9

Maximum value

• The number with the greatest value in the data set
• ⇒ 20.4

Minimum value

• The number with the least value in the data set
• ⇒ 10.1

Range

• Maximum value - Minimum value
• 20.4 - 10.1
• 10.3

Answer 2

The range of a dataset is the distance between the maximum value and the minimum value. The range is found by subtracting the minimum value from the maximum value: maximum - minimum = range.

Maximum value of this dataset = 20.4

Minimum value of this dataset = 10.1

20.4 - 10.1 = 10.3

Range = 10.3

Hope this helps!
