Question

Find the mean absolute deviations (mad) of the data set.

Answer 1

Step 1:

In this question, we are given the following:

Find the mean absolute deviations (MAD) of the data set.​

Step 2:

First, we calculate the mean of the sample:

`Mean\text{ = }(5+8+11+7+9)/(5)=\text{ }(40)/(5)=\text{ 8}`

Next, we find the absolute mean deviation:

Player Number of pts Mean Mean Deviation Absolute Mean Deviation

Daniela 5 8 -3 3

Isabella 8 8 0 0

Rafaella 11 8 3 3

Beatriz 7 8 -1 1

Kalin 9 8 1 1

Step 3:

From the table above, we can now calculate the mean absolute deviation as:

`Mean\text{ Absolute Deviation = }(3+0+3+1+1)/(5)=\text{ }(8)/(5)=1.\text{ 6}`

Alternatively, using the Mean Absolute Deviation calculator, we have that :

CONCLUSION:

The mean Absolute deviation= 1. 6
