whats the mean absolute deviation of
5.8, 7, 8.1, 9.2, 9.9
To find the mean absolute deviation, first find the mean of the numbers:
(5.8 + 7 + 8.1 + 9.2 + 9.9) / 5 = 40 / 5 = 8
Next, find the absolute deviation for each number by subtracting the mean from each number and taking the absolute value:
|5.8 - 8| = 2.2
|7 - 8| = 1
|8.1 - 8| = 0.1
|9.2 - 8| = 1.2
|9.9 - 8| = 1.9
Then find the mean of these absolute deviations:
(2.2 + 1 + 0.1 + 1.2 + 1.9) / 5 = 6.4 / 5 = 1.28
Therefore, the mean absolute deviation of the numbers 5.8, 7, 8.1, 9.2, 9.9 is 1.28.
