Question

1. Given the four sample proportions 0.69, 0.38, 0.73, and 0.4, determine the MAD statistic. Round your answer to 3 decimal places, e.g. 0.583.

2. Given the three sample proportions 0.27, 0.33, and 0.38, determine the MAD statistic. Round your answer to 3 decimal places, e.g. 0.583.

Answer 1

1)

= X / n

= 2.2 / 4

= 0.55

MAD = | xi - | / n

= |0.69-0.55 | / 4+ |0.38-0.55 | / 4 + |0.73-0.55 | / 4 + |0.4-0.55 | / 4

= 0.16

2)

= X / n

= 0.98 / 3

= 0.327

MAD = | 0.27 - 0.327 | / 3 + | 0.33 - 0.327 | / 3 + | 0.38 - 0.327 | / 3

= 0.038
