What is the absolute deviation for the numbers: 112,145,108,160,122

Absolute deviation is 92.40

Rearrange numbers from least to greatest to avoid confusion.

108, 112, 122, 145, 160

Mean = (108 + 112 + 122 + 145 + 160) / 5

= 647 / 5

= 129.40

Absolute deviation : (number - mean)

*absolute means that a number is always treated as a positive number contrary to its actual value

108 - 129.40 = 21.40

112 - 129.40 = 17.40

122 - 129.40 = 7.40

145 - 129.40 = 15.60

160 - 129.40 = 30.60

total absolute deviation 92.40

Mean absolute deviation = 92.40 / 5 = 18.48
