Question

Find the MAD for both citys and then round your answer to the nearest tenth



City A: 3.5, 4, 4, 2, 5.5, 5



City B: 5, 6, 3.5, 4, 5.5, 6



The steps to find the MAD include: 1. find the mean (average). 2. find the difference between each data value and the mean. 3. take the absolute value of each difference. 4. find the mean (average) of these differences.

Answer 1

Answer:

A: ⅚

B: ⅚

Step-by-step explanation:

City A: 4, 3.5, 5, 5.5, 4, 2

Mean: sum/n

= 24/6 = 4

|x - mean|: 0, 0.5, 1, 1.5, 0 , 2

MAD = sum|x - mean|/n

5/6 = 0.833

City B: 5, 6, 3.5, 5.5, 4, 6

Mean: 30/6 = 5

|x - mean|: 0, 1, 1.5, 0.5, 1, 1

MAD = sum|x - mean|/n

5/6 = 0.833
