Question

​Given the three sample proportions 0.22, 0.31, and 0.42, determine the MAD statistic. Round your answer to 3 decimal places, e.g. 0.583.

Answer 1

Answer:

Given,

To determine the MAD statistic

The sample proportions are 0.22, 0.31 ,0.42

Here we can compute the MAD statistic as follows

MAD = ( |0.22 - 0.31| + |0.22 - 0.42| + |0.31 - 0.42| ) / 3

= (0.09 + 0.2 + 0.11)/3

= 0.4/3

MAD statistic = 0.133
