Question

The number of lawns the workers in Angelo’s company have mowed in the first 6 weeks of the summer is 31, 24, 32, 28, 29, and 36. What is the mean absolute deviation for the number of lawns mowed in the first 6 weeks of summer?

Answer 1

Answer: MAD= 3

Explanation:

Find the mean of the data set

31+24+32+28+29+36/6= 30

subtract EACH data by the mean, find the absolute value of the answer

31-30= 1 (absolute value)

24-30= 6 (absolute value)

32-30= 2 (absolute value)

28-30= 2 (absolute value)

29-30= 1 (absolute value)

36-30= 6 (absolute value)

Now find the mean of the values

1+6+2+2+1+6/6=3

MAD=3
