M = 11+16+9+21+13+10+10+12+13/9

= 115/9

= 12,77

Jawaban:

12,7777777778

Penjelasan dengan langkah-langkah:

Mean = Jumlah data ÷ banyak data

11, 16, 9, 21, 13, 10, 10, 12, 13

= 9 + 10 + 10 + 11 + 12 + 13 + 13 + 16 + 21

= 115 (jumlah data)

115 (jumlah data) ÷ 9 (banyak data)

= 12,7777777778
