YOU'LL GET BRAINLIEST!
Rin incorrectly calculated the mean absolute deviation for the data set 25,25,31,36,38.Her work is shown here.
1. Find the mean.
Mean =
25 + 25 + 31 + 36 + 38
5
=
155
5
= 31
2. Find each absolute deviation.
Absolute deviations:6,6,0,5,7
3. Find the mean absolute deviation.
MAD =
6 + 0 + 5 + 7
4
=
18
4
= 4.5
In which step did Rin make an error?
