Answer 2

b. 0.031

Average deviation

To find the average deviation of the given values, we have to follow the below-mentioned steps:

• Find the mean of all the numbers

      (16.23 + 16.22 + 16.30 + 16.25) = 65

      65/4 = 16.25

• Find individual absolute deviation using the formula

      |16.23 – 16.25| = 0.02

      |16.22 – 16.25| = 0.03

      |16.30 – 16.25| = 0.05

      |16.23 – 16.25| = 0.02

      |16.25 – 16.25| = 0

• Now add all the values found in step 2

      0.02+0.03+0.05+0.02+0 = 0.12

• Divide it by the number of values in the data set

       0.12/4 = 0.03

Hence, the average deviation for mean for the following values 16.23, 16.22, 16.30, and 16.25 is 0.03.
