Penjelasan dengan langkah-langkah:
nilai rata rata
= 7 + 7 + 4 + 6 + 8 + 5 + 6 + 4 + 5 + 5 + 4 + 6 + 9 + 5 + 4/15
= ( 4 x 4 ) + ( 4 x 5 ) + ( 3 x 6 ) + ( 2 x 7 ) + ( 1 x 8 ) + ( 1 x 9 )/15
= 16 + 20 + 18 + 14 + 8 + 9 / 15
= 85/15
= 5,67
maka, banyak siswa yang nilainya di atas rata rata
= 3 + 2 + 1 + 1
= 7
