Find the means of these numbers 3,7,2,9,4,7,3,7,5,2

First to find the mean of the numbers we have to add the all up

3 + 7 + 2 + 9 + 4 + 7 + 3 + 7 + 5 + 2 = 49

Then we have to divide by how many numbers we have which is 10

49 divided by 10 equals 4.9

4.9 is the mean of the data set.

The "mean" of a group of numbers is also called their "average".

To calculate the mean, add up all the numbers, then

divide the sum by the number of items on the list.

Step #1: Addum up: 3+7+2+9+4+7+3+7+5+2 = 49

Step #2: Count the number of items on the list: I count 10.

Step #3: Divide the sum by the number of items on the list.

49 / 10 = 4.9

The mean (average) of the numbers on that list is 4.9.
