To find the mean of a data set, add up all the numbers in the set and then divide the sum by the total number of values in the set.
Sum of the numbers: 4 + 1 + 1 + 7 + 5 + 2 + 8 = 28
Total number of values: 7
Mean = Sum of the numbers / Total number of values = 28 / 7 = 4
Therefore, the mean of the given data set is 4.
find the mean of the following data set:
4, 1, 1, 7, 5, 2, 8
