Question

What is the mean of the mean of the data plot set below?

12,15,10,11

Answer 1

To find the mean, you add all the numbers given (12, 15, 10, and 11) and then divide by the number of values in the set (in this case, 4). This is the same as finding an average. To do this, you add 12 + 15 + 10 + 11 = 48. Since you have 4 numbers, you do 48 ÷ 4, which equals 12. Therefore, the mean is 12.

Answer 2

Explanation:

Your mean would be 12.

You add up all the numbers:

12+15+10+11=48

Then you divided the sum by however many numbers there are, there are 4:

48 divided by 4 = 12
