Umur ( thn): 1,2,3,4,5
frekuensi : 1,4,6,11,18
jawab:

Answer 1

1 x 1  =  1
2 X 4  =  8
3 X 6  = 18
4 X 11 = 44
5 X 18 = 90
Jumlah = 161
Mean = 161/ 40 = 4,025
median = 4
Modus = 5

Answer 2

1 × 1 = 1
4 × 2 = 8
6 × 3 = 18
11 × 4 = 44
18 × 5 = 90

mean = jumlah data/banyaknya datum
= 161/40
= 4,025
Median = 4 + 4/2 = 4
Modus = 5 (muncul 18 kali)
