The following observations have been arranged in ascending order. If the median of the data is 63, find the value of x.
29, 32, 48, 50, x, x + 2, 72, 78, 84, 95
Solution:
Total number of observations
which is an even number.
Therefore, median is the mean of
and
observation.
observation =
observation = 5th observation = x
observation =
observation = 6th observation = x+2
Median = mean of 5th and 6th observation
It is given that median = 63.
Therefore, Median
