Find the mean for the given set of data.

18, 15, 22, 18, 25, 19, 23

20

The answer is 20 (the mean is 20).

When finding the mean (average), you have to add up all the numbers. (So 18+15+22+18+25+19+23+20 which equals 160). Then, you have to divide that number by the total number of numbers in the data set. (So 160 divided by 8, which equals 20). So, the mean of this data set is 20.

Answer: 20

Step-by-step explanation:

You find the mean by adding up all the numbers in a data set, then dividing by the number added.

18 + 15 + 22 + 18 + 25 + 19 + 23 + 20 = 160

We added 8 numbers together, so we divide 160 by 8

160/8 = 20
