Question

The median of 19 observations is 30. Two more observations are made and the values are 8 and 32. Find the median of the 21 observations taken together.

Answer 1

Given observations in ascending order are: 11,13,15,19,x+2,x+4,30,35,39,46

Therefore the median is the average of (x + 2) and (x + 4)

Median = (x +2 + x + 4)/2 = x + 3

Given median = 25

Hence x + 3 = 25

Therefore, x = 22
