Solution:-
To find the median arrange the given observations in ascending order,
Total number of observations =
Then,
Median = (
observation +
observation)/
observation =
observation =
Median =
=
=
finding the absolute values of the respective deviations from the median, i.e.,
are
Finding Mean Deviation,
M.D (M)=
=
=
Therefore, the mean deviation about the median for the given data is
.
