Question

Median of the data 6 10 20 x 12 14 is 12 then x is equal to

Answer 1

Median when no of terms are even is given by

No of terms, n = 6

M = [ ( n term / 2 ) + ( n term/2 + 1 ) ] / 2

12 = [ ( 6 / 2 ) + ( 6/2. + 1 ) ] / 2

12 = [ 3rd term + 4th term ] / 2

12 = [ 20 + x ] / 2

24 = 20 + x

24 – 20 = x

4 = x
