Arrange in ascending order 3, 3, 6, 6, 6, 6, 6, 9, 9, 9, 10, 12, 12, 15, 15 . There are a total of 15 numbers If there are a total of n numbers, then Median= (50% of (n+1))th number Hence, median in this case= (50% of (15+1))th number Median= (50% of 16)th number = 8th number = 9 In the arrangement of numbers above, 8th number is 9. Hence, the median is 9
