100 ada 6 orang
TOTAL SISWA = 4 + 8 + 8 + 10 + 6 + 6 = 42 orang
Mean = Jumlah data : banyak data
= 75 + 75 + 75 + 75 + 80 + 80 + 80 + 80 + 80 + 80 + 80 + 80 + 85 + 85 + 85 + 85 + 85 + 85 + 85 + 85 + 90 + 90 + 90 + 90 + 90 + 90 + 90 + 90 + 90 + 90 + 95 + 95 + 95 + 95 + 95 + 95 + 100 + 100 + 100 + 100 + 100 + 100 : 42
= 3690 : 42
= 87,85 (C)
