Explanation:

Givens

We are given a data set:

`18,28,24,25,15`

We are asked to find the mean of this data set (in other words, find the average).

Solve

First, count how many data values there are:

`1. \ 18\\2. \ 28\\3. \ 24\\4. \ 25\\5. \ 15`

Then, add up the data values:

`18+28+24+25+15=110`

Then, divide the sum of the data values by the number of data values present:

`\displaystyle (110)/(5)=22`

Final Answer

Therefore, the mean of the data set is 22.
