Question

What is the mean absolute deviation of 4.8 5.9 6.2 10.8 1.2 6.4

Answer 1

To find the mean absolute deviation, we first need to find the mean of the numbers given:

Mean = (4.8 + 5.9 + 6.2 + 10.8 + 1.2 + 6.4) / 6
Mean = 35.3 / 6
Mean = 5.8833333

Next, we find the absolute difference between each number and the mean:

|4.8 - 5.8833333| = 1.0833333
|5.9 - 5.8833333| = 0.0166667
|6.2 - 5.8833333| = 0.3166667
|10.8 - 5.8833333| = 4.9166667
|1.2 - 5.8833333| = 4.6833333
|6.4 - 5.8833333| = 0.5166667

Now, we find the mean of these absolute differences:

Mean absolute deviation = (1.0833333 + 0.0166667 + 0.3166667 + 4.9166667 + 4.6833333 + 0.5166667) / 6
Mean absolute deviation = 2.2072222

Therefore, the mean absolute deviation of the numbers 4.8, 5.9, 6.2, 10.8, 1.2, 6.4 is 2.2072222.

Answer 2

round to the nearest tenth

Answer 3

When rounded to the nearest tenth, the mean absolute deviation of the numbers 4.8, 5.9, 6.2, 10.8, 1.2, and 6.4 is 2.2.
