Question

If The median of the data is 63.find the value of x. Data.29,32,48,50,x,x+2,72,78,84,95

Answer 1

to find median
first arrange it in ascending order (already done)
29 32 48 50 x x+2 72 78 84 95
no. of elements is 10
so (10/2th+ 10/2 +1 the)/2
( 5th+6th )/2
x+x+2/2
2x+2/2=63
2x+2=126
2x=124
x=62

Answer 2

Median for even no. of data is average of the values at position [n /2] and [(n / 2) +1]

So here median values are 10/2 =5 & (10/2)+1=6

Values at 5th & 6th position are x & x+2 respectively  

So, [ (x) + (x+2) ] / 2 = 63

(2x+2) /2 = 63  

x+1 = 63  

x = 62
