Question

What is the mean (average) and range (difference between highest & lowest values) for the following list of numbers: 5, 3, 9, 1, 4, 2

Answer 1

Mean = 4

Range = 8

Explanation:

Order the numbers numerically.

1, 2, 3, 4, 5, 9

Mean: Add all the number together. 1 + 2 + 3 + 4 + 5 + 9 = 24

Divide by the number of numbers. 24 divided by 6 = 4, the mean is 4.

Range: Identify the smallest number and the largest number.

Lowest: 1, Highest: 9

Subtract the smallest number by the largest. 9 - 1 = 8, the range is 8.
