Question

find the median of the following data 19 , 25 , 59 , 48 , 35 , 31 , 30 , 32 , 51.if 25 is replaced by 52 and 19 by 29 , what will be the new median

Answer 1

Heya !!!

this is your answer.....

Given data .....

19, 25, 59, 48, 35, 31, 30, 32, 51.

Median is the middle value after arranging the data in ascending or descending order.

So.....

Arranging the data in ascending order. .....

19, 25, 30, 31, 32, 35, 48, 51, 59.

Number of terms, n = 9.

Median term = (n+1)/2
= 10/2
= 5.
Hence 5th term is the median.
So median = 32.

If 51 is replaced with 25 and 19 by 29. ...

25, 25, 29, 30, 31, 32, 35, 48, 59.

So....
As n is same ...
So median is the 5th term i.e. 31.

Hope it helps
