Question

median of 5 7 15 17is

Answer 1

Given data = 5,7,15,17

Number of observations =4

Median of Given data is mean of (n / 2, n /2 + 1) th terms.

Median = Mean of 4/2, 4/2 + 1 terms

= Mean of 2nd, 3 Rd terms

= Mean of 7, 15

=7+15/2

= 11

Hence, median =11

Answer 2

Hi friend!!!!
------------------------------------------------------------------------------
First, the nos. are arranged in ascending order- 5,7,15,17 
n=4
Median = (4/2) th term + (4/2 +1) th observation 
                ____________________________
                                          2
             = 2nd term +  3rd observation
               _______________________
                                    2
             = 7+15
                _____
                   2
             = 22/2
             = 11

So, the median is 11.
