What is the absolute davatation round to the nearest tenth for 6.3, 6.4, 6.5, 6.6, 6.8. 6.8, 7.5?

Let's find the mean of all the values first.

6.3+6.4+6.5+6.6+6.8+6.8+7.5 = 46.9

Let's divide by the number of values.

46.9:7=

6.7

Now let's find the distance that each number is away from 6.7 and find the mean of those numbers.

0.4+0.3+0.2+0.1+0.1+0.1+0.8=

.2857

≈ 0.3

So, the absolute deviation is 0.3.
