Question

find the median of 10, 32 ,17, 19, 21, 22, 9, 35

Answer 1

First arrange the observations in either increasing or decreasing order

9 , 10 , 17 , 19 , 21 , 22 ,32 , 35

Here there are 8 terms ( 8 is even)

So median = mean of ( 8/2 , 8/2+1 terms )

= Mean of ( 4 , 5 terms)

= 19 + 21 / 2

= 40/2 .

= 20 .

Therefore, Median is 20

Answer 2

Hello..

First of all arrange this data in ascending order...

9 , 10 , 17 , 19 , 21 , 22 , 32 , 35

Total nos. are 8

hence, n = 8

n = even

Median = (8/2, 8/2+1)

(8/2 = 4 , 8/2 = 4 + 1 = 5)

4th term is 19

5th term is 21

19 + 21/2

40/2

20
