The median of a set of 9 distinct observations is 20.5.

Question

The median of a set of 9 distinct observations is 20.5. If each of the largest 4 observations of the set is increased by 2, then the median of the new set

Accepted Answer

Here total no of observation is 9 which is a odd number. As we know for odd number 9 the median will be the 5th term.

Now question says, you increase largest 4 number by 2 which does not affect the 5th term so the new median will be the same.
