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 .
