Penjelasan dengan langkah-langkah:
Urutan data
53, 54, 57, 59, 62, 64, 65, 69, 69, 71, 72, 75, 78, 78, 83
Nilai terendah [ R ] = 53
Q1 = 59
Median / nilai tengah = 69
Q2 = 75
Nilai tertinggi [ T ] = 83
1) Jangkauan = T – R
Jangkauan = 83 – 53
2) simpangan kuartil = ½(Q3 – Q1)
simpangan kuartil = ½(75 – 59)
simpangan kuartil = ½ × 16
simpangan kuartil = 16/2

Jawaban:
1. Jangkauan = 30
2. Simpangan kuartil = 8
Penjelasan:
Susun terlebih dahulu data
83, 53, 54, 78, 78, 57, 59, 65, 62, 69, 75, 72, 69, 71, 64
dari yg terkecil
53, 54, 57, 59, 62, 64, 65, 69, 69, 71, 72, 75, 78, 78, 83
ada 15 data, maka
-> n = 15
------------
Ditanya:
1. jangkauan, lihat mana data terbesar dan terkecil
53, 54, 57, 59, 62, 64, 65, 69, 69, 71, 72, 75, 78, 78, 83
terkecil terbesar
maka,
jangkauan = data terbesar-data terkecil
jangkauan = 83 - 53
jangkauan = 30
------------------------------
2. simpangan kuartil
q1 = (n+1)/4 = (15+1)/4 = 16/4 = 4 (data ke-4)
53, 54, 57, 59, 62, 64, 65, 69, 69, 71, 72, 75, 78, 78, 83
data_q1 = 59
dan
q3 = 3(q1) = 3(4) = 12 (data ke-12)
53, 54, 57, 59, 62, 64, 65, 69, 69, 71, 72, 75, 78, 78, 83
data_q3 = 75
simpangan kuartil = (data_q3 - data_q1)/2 = (75-59)/2 = 16/2
simpangan kuartil = 8
