Question

The mean of the following dataset is 8. Find the mean absolute deviation of the dataset.

{5.8,7,8.1,9.2,9.9}(1 point)
The mean absolute deviation is _____

Answer 1

wrong

Answer 2

1.08

Answer 3

My apologies for the error. Let's correct it:

To find the mean absolute deviation:

1. Find the absolute difference between each data point and the mean:
|5.8 - 8| = 2.2
|7 - 8| = 1
|8.1 - 8| = 0.1
|9.2 - 8| = 1.2
|9.9 - 8| = 1.9

2. Find the mean of these absolute differences:
(2.2 + 1 + 0.1 + 1.2 + 1.9) / 5 = 6.4 / 5 = 1.28

Therefore, the mean absolute deviation of the dataset {5.8, 7, 8.1, 9.2, 9.9} is 1.28.
