Median Formula for Grouped Data

Information :

F = Amount of frequencies before the median

f = Frequency of median class

c = Class length

n = Sum of frequencies

be = Bottom edge of median class

Me = Median of data

Example :

Please determine the median value in the table data below !

Answer :

be = 45 - 0,5 = 44.5

n = 8 + 10 + 13 + 17 + 14 + 11 + 7 = 80

F = 8 + 10 + 13 = 31

c = 35 - 30 = 5

f  = 17

So the median of the data is 47.15.
