you dont actually want to calculate the median...for 20 inputs you are gonna waste a lot of time and risk a calculation error in my opinion.

The first graphs there is only only one bar that sticks above the blue line. we know that when we order the scores the median (i.e. the average of observation 5 and 6) will be for sure below the value in the blue line.

The second graph we can see only three observation are below that blue line..surely, the median (i.e. the average of observation 5 and 6) will greater than the blue line. Also recognizing this will help us easily answer the second part of the question.
