Mean Worksheets

The mean is the average of a set of numbers.

It is found by adding up the set of numbers and then dividing the total by the number of data points in the set.

Example 1) Find the mean of 5, 7, 8 and 4

Step 1) Add up the numbers to give a total of 5+7+8+4=24

Step 2) Divide the total by the number of data points. 24 ÷ 4 = 6

Answer: the mean is 6.

Example 2) Find the mean of 8, 2, 5, 7 and 13

Step 1) Add up the numbers to give a total of 8+2+5+7+13=35

Step 2) Divide by the number of data points. 35 ÷ 5 = 7

Answer: the mean is 7.

These printable mean worksheets have been carefully graded to ensure a progression in the level of difficulty.

The first 2 sheets involve finding the mean of 3, 4 or 5 relatively small numbers.

The third sheet involves finding the mean of 3, 4 or 5 numbers up to 100.

The 4th sheet includes negative numbers as well as positive ones.

The Missing Data Point worksheets involve finding a missing data point, when there is one data point missing, and the mean is given.

Example 1) The mean of 4 numbers is 6. Three of the numbers are 4, 8, and 3. What is the 4th number?

Step 1) Add up the 3 numbers to give a total of 4+8+3=15

Step 2) Multiply the mean by the number of data points. 6x4=24

Step 3) The missing data point is the answer from Step 2 subtract the answer from Step 1 which is 25-15=9.

Example 2) Five numbers have a mean of 3. Four of the numbers are 7, 5, 2 and -4. What is the 5th number?

Step 1) Add up the numbers to give a total of 7+5+2+(-4)=10

Step 2) Multiply the mean by the number of data points. 3x5=15

Step 3) The missing data point is the answer to Step 2 - Step 1, which is 15-10=5.
