Question

whats the mean absolute deviation of
5, 6, 8, 9, 10 ,10 , 22

Answer 1

wrong

Answer 2

To calculate the mean absolute deviation, you first need to find the mean of the numbers:

(5 + 6 + 8 + 9 + 10 + 10 + 22) / 7 = 70 / 7 = 10

Next, find the absolute deviation of each number from the mean:

|5 - 10| = 5
|6 - 10| = 4
|8 - 10| = 2
|9 - 10| = 1
|10 - 10| = 0
|10 - 10| = 0
|22 - 10| = 12

Now, find the mean of these absolute deviations:

(5 + 4 + 2 + 1 + 0 + 0 + 12) / 7 = 24 / 7 ≈ 3.43

Therefore, the mean absolute deviation of the numbers 5, 6, 8, 9, 10, 10, 22 is approximately 3.43.

Answer 3

I apologize for the mistake in my previous response.

To find the mean absolute deviation, you first need to calculate the mean of the numbers:

(5 + 6 + 8 + 9 + 10 + 10 + 22) / 7 = 70 / 7 = 10

Next, find the absolute deviations of each number from the mean:

|5 - 10| = 5
|6 - 10| = 4
|8 - 10| = 2
|9 - 10| = 1
|10 - 10| = 0
|10 - 10| = 0
|22 - 10| = 12

Now, calculate the sum of these absolute deviations:

5 + 4 + 2 + 1 + 0 + 0 + 12 = 24

Divide this sum by the total number of data points (7 in this case) to find the mean absolute deviation:

Mean Absolute Deviation = 24 / 7 ≈ 3.43

Therefore, the correct mean absolute deviation of the numbers 5, 6, 8, 9, 10, 10, 22 is approximately 3.43.
