Question

What is the mean of this data set

14, 12, 21, 26, 19, 15, 22, 17, 24, 18

Answer 1

The mean of this data set is 18.8

Answer 2

The mean of this data set is
`\mu = 18.8`

Explanation:

By definition, the mean of a data set
`x_1, x_2, x_3, ..., x_n` is

`\mu = (\sum^n_i x_i)/(n)`

Where n is the total number of data.

In this case we have 10 data

14, 12, 21, 26, 19, 15, 22, 17, 24, 18

So the mean is:

`\mu = (14 +12 +21 +26 +19 +15 +22+ 17 +24 +18)/(10)`

`\mu = 18.8`
