Question

The following observations have been arranged in ascending order. If

the median of the data is 63, find the value of x.

29, 32, 48, 50, x, x + 2, 72, 78, 84, 95​

Answer 1

n=10

median= {n/2th observation +(n/2+1)th observation}/2

= {10/2th observation+10/2+1th observation}/2

= (5th observation+ 6th observation)/2

= (x+ x+2)/2

= (2x+2)/2

= x+1

ATP,

x+1=63

x=63-1

x=62

Value of the x is 62
