A. Mean = ∑nilai × frekuensi / ∑frekuensi
Mean = (0×1) + (2×3) + (3×2) + (4×4) + (5×1) / 1 + 3 + 2 + 4 + 1
Mean = 0 + 6 + 6 + 16 + 5 / 11
Mean = 33/11
Mean = 3
Susunan data berurut : 0, 2, 2, 2, 3, 3, 4, 4, 4, 4, 5
Modus (nilai/angka yang sering muncul) = 4
Median = 3
B. Mean = ∑nilai × frekuensi / ∑frekuensi
Mean = (4×4) + (5×5) + (6×9) + (7×12) + (8×6) + (9×3) + (10×1) / 4 + 5 + 9 + 12 + 6 + 3 + 1
Mean = 16 + 25 + 54 + 84 + 48 + 27 + 10 / 40
Mean = 264/40
Mean = 6,6
Modus = 7
Median = (12+12) / 2
Median = 24/2
Median = 12
