The mean absolute deviation of the data set is 6

Step-by-step explanation:

To find the mean absolute deviation of the data, start by finding the mean of the data set.

∵ The data are 68 , 59 , 65 , 77 , 56

- Find their sum

∴ The sum of the data = 68 + 59 + 65 + 77 + 56 = 325

∵ The number of data in the set is 5

- Find the mean by dividing the sum of the data by 5

∴ The mean = 325 ÷ 5 = 65

- Find the absolute difference between the each data and the mean

∵ I68 - 65I = 3

∵ I59 - 65I = 6

∵ I65 - 65I = 0

∵ I77 - 65I = 12

∵ I56 - 65I = 9

- Find the sum of the absolute differences

∵ The sum of the absolute differences = 3 + 6 + 0 + 12 + 9

∴ The sum of the absolute differences = 30

Divide the sum of the absolute differences by 5 to find the mean absolute deviation

∴ The mean absolute deviation = 30 ÷ 5 = 6

The mean absolute deviation of the data set is 6
