Jawab:
kuartil bawah = 5,5
median = 6
kuartil atas = 7
Penjelasan dengan langkah-langkah:
*urutkan 5,5,6,6,6,7,7,7,8
n = 9
*kuartil bawah = (n+1)/4
10/4 = urutan ke 2.5 = (5 + 6) / 2 = 5,5
*median = nilai tengah = n/2
9/2 = urutan ke 4,5 = 6
*kuartil atas = 3(n+1)/4
30/4 = urutan ke 7,5 = (7+7) / 2 = 7
