1.Dari data 40,25,30,25,35,30,25,25,40,40 Tentukan Q1, Q2, Q3, Jangkauan Interkuartil dan Simpangan Kuartil 2.Dari data berikut, tentukan Q1, Q2, Q3, Jangkauan

1. 25,25,25,25,30,30,35,40,40,40.
Q2= 30 Q1= 25 Q3 = 40
simpangan kuartil = ½(Q3 - Q1)
= ½(40-30) = ½x10 = 5
jangkauan interkuartil = Q3 - Q1 = 40-30 = 10

2. 3,3,4,4,4,4,5,5,5,6,6,7,7,8,8,8
Q2 = 5 Q1 = 4 Q3 = 7
simpangan kuartil = ½(Q3-Q1)
= ½ (7-4) = ½x3 = 1,5
jangkauan kuartil = Q3 - Q1
= 7 - 4 = 3
