Calculate the mean deviation about median for the following data
The observations are already in ascending order.
Let's calculate the cumulative frequencies
Median of the observations would be average of 9th and 10th readings =9th term+10th term2=10+102=10
Let's calculate fi|xi−M| for given observations.
Mean deviation about median=M.D(M)=∑ni=1fi|xi−M|∑ni=1fi
