Question

tolong kak dengan caranya yang ada di gambar :)​

Answer 1

Penjelasan dengan langkah-langkah:

10, 7, 6, 8, 8, 9, 8, 7, 8, 7, 9, 9

diurutkan

6, 7, 7, 7, 8, 8, 8, 8, 9, 9, 9, 10

6, 7, 7, | Q1 | 7, 8, 8 | Q2 | 8, 8, 9, | Q3 | 9, 9, 10

Q1 = (7 + 7)/2

Q1 = 14/2

Q1 = 7

Q3 = (9 + 9)/2

Q3 = 18/2

Q3 = 9

Qd = 1/2 . (Q3 - Q1)

Qd = 1/2 . (9 - 7)

Qd = 1/2 . 2

Qd = 1

Answer 2

statistik

urutkan data

6, 7, 7, 7, 8, 8, 8, 8, 9, 9, 9, 10

n = banyak data = 12

Q3 = 3/4 (n + 1)

Q3 = 3/4 (12 + 1)

Q2 = 9 3/4

letak Q3 → antara data ke 9 dan data ke 10

Q3 = (d9 + d10)/2

Q3 = (9 + 9)/2

Q3 = 9

Q1 = 1/4 (n + 1)

Q1 = 1/4 (12 + 1)

Q1 = 3 1/4

letak Q1 → antara data ke 3 dan data ke 4

Q1 = (d3 + d4)/2

Q1 = (7 + 7)/2

Q1 = 7

Qd = (Q3 - Q1)/2 = (9 - 7)/2 = 1
