Nilai = 6,7,8,9 Frekuensi = 10,12,8,5. Tentukan kedudukan antar mean, modus, dan median, dari data di atas ?

Modus = 7
Median = 7
Mean = (6.10)+(7.12)+(8.8)+(9.5)/35 = 253/35 = 7,2

...N ......F.........N× F
...6.......10..........60
...7........12..........84 => kelas modus & median
...8.......8...........64
...9........5..........45
------------------------- +
.30.................253
--------------------------

Mean = € NF/ € N
Mean = 253/30
Mean = 8,43

Modus = Nilai yang F nya terbesar
Modus = 7

(1/2)F = (1/2)×253 = 126,5 = 127
Median = Nilai yang terletak di 1/2F
Median = Nilai yang terletak baris F nya 127
Median = 7
