Mean Median Mode Range

The mean is the average of a set of numbers, calculated by adding all the numbers together and dividing by the total count of numbers.

Add the numbers: 4 + 5 + 5 + 2 + 3 + 3 + 2 + 8 = 32. Then divide by the count of numbers (8): 32 ÷ 8 = 4.

The median is the middle number in a sorted list of numbers. If there are two middle numbers, add them together and divide by 2.

First, sort the numbers: 1, 2, 3, 4. The two middle numbers are 2 and 3. Add them: 2 + 3 = 5, then divide by 2: 5 ÷ 2 = 2.5.

The mode is the number that appears most frequently in a set of numbers.

The range is the difference between the largest and smallest numbers in a set.

Identify the largest number (20) and the smallest number (5). Then subtract: 20 - 5 = 15.

Mean = (Sum of all values) ÷ (Number of values).

Range = Largest score (108) - Smallest score (60) = 108 - 60 = 48.

Add them together and divide by 2.
