Find the mad: a) 65,61, 62, 66, 71

b) 60, 80, 75, 65

N=5

MAD=2.8

Step-by-step explanation:

Step 1 : Find the mean of the data:

- 65+61+62+66+71 = 5=325/5=

Step 2 : Find the distance between each data and mean.

Distance between 65 and 65 is 0

Distance between 61 and 65 is 4

Distance between 62 and 65 is 3

Distance between 66 and 65 is 1

Distance between 71 and 65 is 6

Step 3 : Add all the distances:

0+4+3+1+6=14

Step 4 : Divide it by the number of data:

14/5=2.8

n = Number of values
