Question

Find the mean of the numbers 10, 11, 12, 14, 12, 11, 13, 12, 14, and 11.

Answer 1

mean = 12

Explanation:

the mean of a data set is calculated as

mean =
`(sum)/(count)`

sum = 10 + 11 + 12 + 14 + 12 + 11 + 13 + 12 + 14 + 11 = 120

there are 10 values, so count = 10

Then

mean =
`(120)/(10)` = 12
