30-35..........2
36-41........25
42-47......100 -> kelas median
48-53........60

-----------------------
jumlah ....197
L1 = 41,5
N = 197
jumlah f1 = 2 + 25 = 27
f median = 100
C = (35 - 30) + 1 = 6
Median
= L1 + (N/2 - jumlah f1)/f median × C
= 41,5 + (197/2 - 27)/100 × 6
= 41,5 + (98,5 - 27)/100 × 6
= 41,5 + 71,5/100 × 6
= 41,5 + 4,29
= 45,79
