Question

What is the mean absolute deviation for 9, 7, 6, 8, 7, and 5?

Answer 1

Given

`9,7,6,8,7,5`

Mean

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

`Mean=(9+7+6+8+7+5)/(6)=(42)/(6)=7`

Standard deviation

Recall

`SD=\sqrt{(10)/(6)}=\:1.29099`
