Rin incorrectly calculated the mean absolute deviation for in which step did Rin make an error?
the data set 25,25,31,36,38.Her work is shown here.
1. Find the mean.
Mean - 25 - 25 31+ 36 38 - 155 31
2. Find each absolute deviation.
Absolute deviations:6,6,0,5,7
3. Find the mean absolute deviation.
MAD = 6 + 0 +5.7 - 18 - 4.5
