Question

Find the mean absolute deviation of the set of data 2,4,5,5,3

Answer 1

1.04

Explanation:

Mean: 2 + 3 + 4 + 5 + 5 = 19/5 = 3.8

3.8 - 2 = 1.8

3.8 - 3 = 0.8

3.8 - 4 = 0.2

3.8 - 5 = 1.2

3.8 - 5 = 1.2

Mean absolute deviation: 0.2 + 0.8 + 1.2 + 1.2 + 1.8 = 5.2/5 = 1.04

Answer 2

3.8

Explanation:

Add up all the numbers in the data set, then divide by how many numbers there were in the data set. In this case there was 5 numbers.
