THE MEAN (AVERAGE)

The mean is what most people call the 'average'. To find it: add all the numbers together, then divide by how many numbers there are. Mean = total ÷ count. For example, the mean of 4, 8, 6 is (4+8+6) ÷ 3 = 18 ÷ 3 = 6.

Find the mean of 4, 6, 8

1Add all: 4 + 6 + 8 = 18

2Divide by how many: 18 ÷ 3 = 6

3Mean = 6

= 6

LEADER TIP
