I have to calculate the MEDIAN using the mean of the class intervals (class midpoint).
I don't have to use any FORMULA
I have this data (the Time numbers are the class midpoint)
N = 38
(The classes are 0-3 , 3-6, 6-9, 9-12 , but I don't have to use them for this exercise, ONLY THE CLASS MEAN)
So, the QUestion is how to calculate the MEDIAN ??
I hope you understand my exercise
