Answer 14

@ajanijones
Do you know how to calculate mean absolute deviation (MSD)?

Answer 15

* MAD

Answer 16

Here's a useful link:

If you do the calculations, you will be able to do them by yourself in your next test.

Answer 17

No I dont.

Answer 18

steps:
1. Find the mean of the dataset
2. Find the absolute difference from the mean (i.e. always positive)
3. Add the differences and divide by the number of values in the dataset. This is the mean absolute difference.

Answer 19

Read through the link, and follow the instructions I gave earlier.
Find the value of the MAD and then compare with the available choices.
