If the mean of set is 20, what is the median of set ?
1.In set there are as many numbers larger than 20 as there are numbers smaller than 20.
2.All numbers in set are even integers
To date i thought when a set of numbers is equally spaced then MEAN = MEDIAN.So knowing one you can find the other. when i saw statement two i picked it.
But answer was E.
It gave an example it does not have to be .14,18,24,24 . The median is 21; 18,18,22,22. The median is 20.
My question : Is their a generalised condition we can add such that number of elements is odd and set of numbers is equally spaced then MEAN = MEDIAN. Please advise.
