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

Answer:

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

Step-by-step explanation:

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

$\mu = \frac{\sum^n_i x_i}{n}$

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:

$\mu = \frac{14 +12 +21 +26 +19 +15 +22+ 17 +24 +18}{10}$

$\mu = 18.8$
