Hi there, this formula made into an array is not excluding empty cells. Any ideas?
{=MEDIAN(IF(A$2:A$50000=A2,IF(B$2:B$50000=B2,C$2:C $50000)))}

column A and column B are categories, column C is the number. I want the median of all rows where a and b are equal, and c is not empty.

in this simple example with only one a+b combo, zy median should return the number 2. Using the array, it is returning 1.5

a b c
