Nilai | 3 | 4 | 5 | 6 | 7 | 8
Frek.| 3 | 5 | 6 | 4 | 5 | 2

Mean
= (3×3 + 4×5 + 5×6 + 6×4 + 7×5 + 8×2) ÷ (3 + 5 + 6 + 4 +5 + 2)
= (9 + 20 + 30 + 24 + 35 + 16) ÷ 25
= 134 ÷ 25
= 5,36

Median
3,3,3,4,4,4,4,4,5,5,5,5,5,5,6,6,6,6,7,7,7,7,7,8,8

Jumlah data: 25
Angka median = ½(25) = 12,5

Angka ke 13 = 5
Median = 5
