Question

Amie works part-time at McDonalds. Each week, her work schedule changes. The number of hours she works each week is shown in the list below. 8, 12, 12, 25, 10, 14, 4, 3, 22, 10 What is the mean absolute deviation of the hours she works each week?

Answer 1

Mean Deviation = 5

Explanation:

The numbers are given as;

8, 12, 12, 25, 10, 14, 4, 3, 22, 10

Mean = Sum of numbers / Population = 120 / 10

Mean = 12

mean deviation involves finding the sum of the absolute values of the differences between the individual elements and the mean. Then divding by the population.

Mean Deviation = |(8 - 12) + (12 - 12) + ( 12 - 12) + (25- 12) + (10- 12) + 14- 12) + (4- 12) + (3 - 12) + (22- 12) + (10- 12)

| / 10

Mean Absolute Deviation = 5
