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

Solution

Since, 8 is less than 30 and 32 is more than 30, so the middle value remains unchanged.

Thus, the median of 21 observations taken together is 30.
