Question

If the observations 6,7,x-2,x,17,20 are written in ascending order and their medium is 16. Find the value of x

Answer 1

there are 6 numbers means t
it is even so for even numbers median = (n/2)+ (n+1/2)th term so 16=(X+X-2)/2 then 2x-2=32 so 2x=34 and x=17 now put this value on the table x-2=15&x=17 so the observations are 6,7,15,17,17,20. here n is used for the middle term.
