38,36,39,37,38,37,38,39,38,37,40,37,38,39,40,39,36,38,37,36 beserta caranya

Answer 1

Mean (rata2)
(38+36+39+37+38+37+38+39+38+37+40+37+38+39+40+39+36+38+37+36) : 20
=757 : 20 = 37,85

Modus:
38=6
36=3
39=4
37=5
40=2
Modus= 38

Median
36, 36, 36, 37, 37, 37, 37, 37, 38, 38, 38, 38, 38, 38, 39, 39, 39, 39, 40, 40
Median= 38


Maaf kalau salah^^

Answer 2

36=3 , 37=5 , 38=6 , 39=4 , 40=2 , jumlah=20 --mean = (36.3) + (37.5) + (38.6) + (39.4) + (40.2) / 20 = 108+185+228+156+80 / 20 = 754/20 = 37.7 --modus= 38 --median= 38+38 / 2 = 38
