Q3 = L + n/4 - f x c
ket:
Q3 = kuartil atas
L = angka posisi kuartil atas
F = frekuensi kumulatif relatif posisi kuartil atas
c = lebar interval antar kuartil
n = 18 (kuartil atas ada diposisi 3/4 dri data)
c = (n+1)/4 = 19/4
Q3 = 7 + ((18/4) - (11/18)) x (19/4)
= 7 + (4.5 - 0.611) x 4.75
= 7 + 3.44
= 10.44
kuartil atas (Q3) dri data = 10.44
