3 , 4 , 4 , 4 , 5 , 5 , 5 , 6 , 6 , 6 , 6 , 7 , 7 , 8 , 8

Q2 = 6
Q1 = 4
Q3 = 7

Simpangan kuartil = Qd = 1/2 × (Q3 - Q1)
= 1/2 × (7 - 4)
= 1/2 × 3
= 1 1/2

Quartil
3,4,4,4,5,5,5,6,6,6,6,7,7,8,8
Maka Diketahui
Q1=3,4,4,4,5=4
Q2=5,5,6,6,6=6
Q3=6,7,7,8,8=7
Simpangan Kuartil=1/2×(Q3-Q1)
Simpangan Kuartil=1/2×(7-4)
Simpangan kuartil=1/2×3=3/2
