As we learnt in
MEDIAN -
For discrete data:
in case of discrete data let x1,x2,x3......xn
If the number of observations(n) is odd then the median is the value observations after the observations are arranged in ascending or descending order of magnitude.
If n is even then and observations.
-
and
Mean Deviation -
If x1, x2, ...xn are n observations then the mean deviation from the point A is given by :
-
