diketahui :
∑f = 3 + 6 + 4 + 5 = 18
∑fi.xi = ∑( (5,5x 3) + (5,9 x6) + (6,3x4) + (6,5x5)
= ∑(16,5+ 35,4+25,2+32,5)
= 109,6
rerata = ∑fi.xi /∑f = 109,6 /18 = 6,09 kg
semoga membantu

5,5 × 3 = 16,5
5,9 × 6 = 35,4
6,3 × 4 = 25,2
6,5 × 5 = 32,5
= (16,5 + 35,4 + 25,2 + 32,5) ÷ (3 + 6 + 4 + 5)
= 109,6 ÷ 18
= 6,08.
Jawab : 6,08.
