Penjelasan dengan langkah-langkah:
rata² = 225 orang
balita = 200
anak² = 275
remaja = m
dewasa = 300
banyak remaja
rata = jumlah data/frekuensi
rata² = (200 + 275 + m + 300)/4
225 x 4 = 775 + m
900 = 775 + m
m = 900 - 775
m = 125 orang
225 = 200 + 275 + m + 300 /4
225 = 475 + m + 300/4
225 = 775 + m/4
775 + m/4 = 225
775 + m = 225(4)
775 + m = 900
