  • a.28, 28, 32, 31, 29, 32, 34, 37, 35, 37, 39, 37
    diurutkan : 28, 28, 29, 31, 32, 32, 34, 35, 37, 37, 37, 39.
    - Jangkauan : 39 - 28 = 11
    - Q2 : 32 + 34 = 68 ÷ 2 = 34
    - Q1 / Kuartil bawah : 29 + 31 = 60 ÷ 2 = 30
    - Q3 / Kuartil atas : 37 + 37 = 74 ÷ 2 = 37
    - Jangkauan kuartil : 37 - 30 = 7

    b. 15, 7, 13, 11, 16, 10, 13, 9, 8, 10, 16
    diurutkan : 7, 8, 9, 10, 10, 11, 13, 13, 15, 16, 16
    - Jangkauan : 16 - 7 = 9
    - Q2 : 11
    - Q1 / Kuartil bawah : 9
    - Q3 / kuartil atas : 15
    - Jangkauan kuartil : 15 - 9 = 6
