Question

Using the following data, calculate the mean absolute deviation: 7, 2, 8, 5, 9, 9, 5, 6, 8, 1. What is the mean absolute deviation for these data?
a 2.2
b 6
c 6.5
d 8

Answer 1

Answer:

pretty sure the answer is 6

Explanation: Add all the numbers up then divide by how many numbers there are.

Step-by-step: 7 + 2 + 8 + 6 + 9 + 9 + 5 + 6 + 8 + 1

= 60 divided by 10 equals 6

Answer 2

Answer:

The answer is 2.2

Step-by-step explanation:

FINDING THE MEAN

First , find the mean .

You add all the numbers , 7, 2, 8, 5, 9, 9, 5, 6, 8, 1. ( 60 )

Then you divide by ten , or , the total number of the data set . ( 6 )

FINDING THE MEAN ABSOLUTE DEVIATION

You have to determine the distance of each number from the mean .

1 + 4 + 2 + 1 + 3 + 3 + 1 + 0 + 2 + 5

Which equals 22 .

Then , you divide by the number of how many numbers you have in the data set , which would be ten .

22 divided by 10 = 2.2 .
