tolong saya cari langkah2!
1. Lo = 8,95 d₂ = 9 - 6 = 3
d₁ = 9 - 4 = 5 c = 3
Mo = Lo ( d₁ / d₁+d₂ ) c
= 8,95 + ( 5 / 5+3 ) 3
= 8,95 + ( ⅝ ) 3
= 8,95 + 15/8
= 8,95 + 1,875
= 10,825
2. Letak kelas median = Σf/2 = 24/2 = 12
tb = 8,95 f = 9
fk = 7 p = 3
median = tb + ( ½n - fk / f ) p
= 8,95 + ( 12 - 7 / 9 ) 3
= 8,95 + ( 5/3 )
= 8,95 + 1,67
= 10,62
3.
f xi f.xi
3 4 12
4 7 28
9 10 90
6 13 78
2 16 32
24 240
x = 240/24 = 10
