39.5 = 7 -----> 40- 44 = (15-7) = 8
44,5 = 15 ----> 45 - 49 = (27-15) = 12
49,5 = 27 ---> 50 - 54 = (33-27) = 6
Kelas Modus = 45 - 49
fo = 12
f -1 = 8
f+1 = 6
d1= 12-8 = 4
d2 = 12- 6 = 6
C = 5
Mo = Tb + C ( d1/ d1+d2)
Mo = 44,5 + 5 (4/ (4+6))
Mo = 44,5 + 5 (4/10)
Mo = 44.5 + 20/10
Mo = 44.5 + 2
Mo = 46,5
