Data tunggal:
Mean =
Median = nilai tengah
Modus = nilai yg paling sering muncul

Data kelompok:
Mean =
Median =
Modus =
Kuartil =


Simpangan:
Rataan kuartil =
Rataan tiga kuartil =
jangkauan (range) = x maks – x min
Jangkauan antar kuartil (hamparan) = Q3 – Q1
Jangkauan semi antar kuartil (simpangan kuartil):
SK =
Simpangan rata-rata =
Simpangan baku = SB =
Ragam = R = S2
