Question

What’s is the mean absolute deviation for 11 of the data set 11 10 9 12 10

Answer 1

Answer: 0.6

Explanation:

First you must calculate the mean of the data

The average is:

`{\displaystyle {\overline {x}}}=(11 +10 +9 +12 +10)/(5)\\\\{\displaystyle {\overline {x}}}=10.4`

Now you must calculate the difference between the value 11 and the average

`d = |11-{\displaystyle {\overline {x}}}|\\\\d=|11-10.4|\\\\d=|0.6|\\\\d=0.6`

The mean absolute deviation is 0.6
