Penjelasan dengan langkah-langkah:
Mean = jumlah data nilai / jumlah data frekuensi
Mean = 4 . 3 + 5 . 5 + 6 . 6 + 7 . 10 + 8 . 5 + 9 . 1 / 30
= 12 + 25 + 36 + 70 + 40 + 45 / 30
= 218 / 30
= 7.26
Me = data diurutkan, tengahnya
4,4,4,5,5,5,5,5,6,6,6,6,6,6,7,7,7,7,7,7,7,7,7,7,8,8,8,8,8,9
Me = 6 + 7 / 2
= 6.5
Mo = jumlah data terbanyak = 7
Pertanyaan = frekuensi nilai <7.26
yang kurang = 4,5,6,7
3 + 5 + 6 + 10
= 24 orsng = C
