Question

What is the value of x if the median of given data is 18: 15, 16, 17, x+ 2, 19, 20, 21?​

Answer 1

Given data is 6,8,9,15,x,29,25,21,22

The ascending order of data excluding x is 6,8,9,15,21,22,25,29

For median to be 18 ,the middle element should be 18(as the data is odd)

So the only possibility is x=18
