Jawaban:Q1=3,289; Q2=3,91875; Q3==4,4125
Rumus kuartil:
Qi = Tb + [((i/4)n-fk) / fi].p
Jumlah data = n = 39
p = 0,5
Kuartil 1
(i/4)n = (1/4).39 = 9,75
Tb = 3,0 - 0,05 = 2,95
fk = 5
fi = 7
Q1= 2,95 + [(9,75-5)/7] (0,5)
=2,95 + 0,339
=3,289
Kuartil 2
(i/4)n = (2/4).39 = 19,5
Tb = 3,5 - 0,05 = 3,45
fk = 12
fi = 8
Q1= 3,45 + [(19,5-12)/8] (0,5)
=3,45 + 0,46875
=3,91875
Kuartil 3
(i/4)n = (3/4).39 = 29,25
Tb = 4,0 - 0,05 = 3,95
fk = 20
fi = 10
Q1= 3,95 + [(29,25-20)/10] (0,5)
=3,95 + 0,4625
=4,4125
Jadi, jawabannya Q1=3,289; Q2=3,91875; Q3==4,4125

Q1= 2,5+ [(9,75-5)/7] (0,4) =2,5+0,27 =2,77 Q2= 3+[(19,5-12)/8] (0,4) =3+0,375 =3,375 Q3= 3,5+[(29,25-29)/10] (0,4) =3,5+0,37 =3,87 Semoga membantu :)))
