Answer 1

The mean absolute deviation of the data set is 2.5

Explanation:

We need to find mean absolute deviation of the data set:

10,8,10,6,6,2,10,4

First we will find mean of the given data set.

The formula used is:
`Mean=(Sum\:of\:all\:data)/(Number\:of\:data)`

Sum of all data = 10+8+10+6+6+2+10+4 = 56

Number of data = 8

So, mean will be:

`Mean=(Sum\:of\:all\:data)/(Number\:of\:data)\\Mean=(56)/(8)\\Mean=7`

Now, we will calculate the absolute difference between mean and each data value.

|10-7| = 3

|8-7| = 1

|10-7| = 3

|6-7| = |-1| = 1

|6-7| = |-1| = 1

|2-7| = |-5| = 5

|10-7| = 3

|4-7| = |-3| = 3

Now, we will find mean of 3,1,3,1,1,5,3,3

Sum of all data = 3+1+3+1+1+5+3+3 = 20

Number of data = 8

So, mean will be:

`Mean=(Sum\:of\:all\:data)/(Number\:of\:data)\\Mean=(20)/(8)\\Mean=2.5`

So, the mean absolute deviation of the data set is 2.5
