Bab Statistika
Matematika SMP Kelas IX

3, 6, 2, 4, 14, 9, 8 → 2, 3, 4, 6, 8, 9 , 14
2, ||3||, 4, ||6||, 8, ||9||, 14
Q1 = 3
Q2 = 6
Q3 = 9

simpangan kuartil = (1/2) x (Q3 - Q1)
simpangan kuartil = (1/2) x (9 - 3)
simpangan kuartil = (1/2) x 6
simpangan kuartil = 3

3,6,2,4,14,9,8

Diurutkan:
2,3,4,6,8,9,14
Diketahui:
Q1=3
Q2=6
Q3=9

Sk=1/2.(Q3-Q1)
Sk=1/2.(9-3)
Sk=1/2×6
Sk=3
