Open in App
Solution

Step 1: First we arrange the given data in ascending order.

Given , 24,26,16,16,21,17,30,28

16,16,17,21,24,26,28,30

Here, total number of observations =8

Step 2: Finding the median:

Since, 8 is an even number

Median=n2thobservation+n2+1thobservation2, where, n is total number of observations

=82th+82+1th2

=4thobservation+5thobservation2

=21+242

=452=22.5

Hence, the median of the given data is 22.5.
