Question 3
The following observations have been arranged in a scending 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
It can be observed that the total number of observations in the given data is 10 (even number).
Therefore, the median of this data will be the mean of 102 and 102+1.
Median = 5th observation + 6th observation2
⇒63=x+x+22
⇒63=2x+22
⇒63=x+1
⇒x=62
