To find the mean absolute deviation, we first need to find the mean of the numbers.
Mean = (4 + 6 + 5 + 3 + 1) / 5 = 3.8
Next, we find the absolute deviations from the mean for each number:
|4-3.8| = 0.2
|6-3.8| = 2.2
|5-3.8| = 1.2
|3-3.8| = 0.8
|1-3.8| = 2.8
Now we find the mean of these absolute deviations:
(0.2 + 2.2 + 1.2 + 0.8 + 2.8) / 5 = 1.44
Therefore, the mean absolute deviation of the numbers 4, 6, 5, 3, 1 is 1.44.
Find the mean absolute deviation of the following numbers:
4, 6, 5, 3, 1
3.8
7.2
