Question

find the median of the following data 4,8,12,16,20,24,28,32​

Answer 1

18

Step-by-step explanation:

We know that, when n is an even number, median = Mean of the values of the (n/2)th and (n/2 + 1)th observations.

Here, n = 8

.°. Median = [{(n/2)th + (n/2 + 1)th} ÷ 2]

= [{(8/2)th + (8/2 + 1)th} ÷ 2]

= [{4th + (4 + 1)th} ÷ 2]

= [{16 + 20} ÷ 2]

= [36 ÷ 2]

= 18

Hence, the median of the given data is 18.
