Materi : Data dan Statistika
Soal Nomor 1
Banyak Data = 21 data
Jumlah Data = 1.370
---
Mean = 1.370/21 = 65,23809...
Modus = 70 [ f = 6 data ]
Median = ½( n + 1 ) = ½(22) = X11 = 70
Jangkauan = 100 - 30 = 70
Q1 = ¼( n + 1 ) = ¼(22) = X5,5 = 50
Q3 = ¾( n + 1 ) = ¾(22) = X16,5 = 75
H = Q3 - Q1 = 75 - 50 = 25
Qd = ½H = ½(25) = 12,5
Soal Nomor 2
Banyak Data = 35 data
Jumlah Data = 239
---
Mean = 239/35 = 6,8285714...
Modus = 7 [ f = 8 data ]
Median = ½( n + 1 ) = ½(36) = X18 = 7
Jangkauan = 10 - 4 = 6
Q1 = ¼( n + 1 ) = ¼(36) = X9 = 5
Q3 = ¾( n + 1 ) = ¾(36) = X27 = 8
H = Q3 - Q1 = 8 - 5 = 3
Qd = ½H = ½(3) = 1,5
Semoga bisa membantu
