Thank you for the help oobleck, much appreciation :D
did not help !!!!!!!!!!!!!!!!!!!!!
It did for me but the answers I got were
a. 29
b. subtract 29 from each of those
c. 8.4
a. 29
b. subtract 29 from each of those
c. 8.4
Thank you for sharing your answers! However, I would like to point out that the deviation from the mean should be calculated by subtracting the mean from each value (in this case, subtracting 29 from each age), not by subtracting the values from the mean.
Using this method, we can find the deviations to be:
-16
3
-3
-6
10
To find the absolute deviation, we take the absolute value of each deviation, which gives us:
16
3
3
6
10
The mean absolute deviation is then found by adding these values up and dividing by the number of values (n=5):
(16+3+3+6+10)/5 = 8.4
So your answers are correct!
