A math tutorial on finding the mean aka average of a given set of numbers. To find the mean of a set of numbers, you add up all the numbers and then divide that total by the number of numbers you added up.

For this problem, our numbers were 6, 34, 13, 11, 15, 7, and 7. The mean or average is (6 + 34 + 13 + 11 + 15 + 7 + 7)/7 = 93/7 = 13.29. We divided the summation by 7 because there were 7 numbers in the data set.
