tentukan
kuartil bawah, median, kuartil atas, jangkauan kuartil, dan simpangan kuartil

Answer 1

Median = 56
kuartil bawah = = 5         urutan data ke 5 = 44
kuartil atas = (19+1)×3/4= 15                                 urutan data ke 15 = 152
jangkauan = 152 - 44 = 108
simpangan = 1/2 × 108 = 54
