Question

Mean absolute deviation of 23,28,16,25,18,31,14,37​

Answer 1

(MAD) Mean Absolute Deviation: 6.25

Explanation:

Mean: 23 + 28 + 16 + 25 + 18 + 31 + 14 + 37 = 192/8 = 24

24 - 23 = 1

24 - 28 = 4

24 - 16 = 8

24 - 25 = 1

24 - 18 = 6

24 - 31 = 7

24 - 14 = 10

24 - 37 = 13

Mean Absolute Deviation (MAD): 1 + 4 + 8 + 1 + 6 + 7 + 10 + 13 = 50/8 = 6.25

Answer 2
