tolong dicari mediannya aj yg no 4

Median (nilai tengah)
Hitung dulu dari yang terkecil.
10, 10, 10, 11, 11, 11, 11, 11, 11, 11, 12, 12, 12, 12, 12, 12, 12, 12, 12, 12, 13, 13, 13, 13, 13, 13, 14, 14, 14, 14
Median = 12

Mean (rata-rata) = Jumlah nilai / banyaknya nilai
Mean = 30 + 77 + 120 + 78 + 56 / 30
Mean = 12

Modus (paling banyak muncul) = 12.
Caranya cari aja siswa yg paling banyak.

Rata rata
= (10x3)+(7x11)+(10x12)+(6x13)+(4x14)/30
= 30+77+120+78+56/30
= 361/30
= 12,03

Modus = 12

Median
=10,10,10,11,11,11,11,11,11,11,12,12,12,12,12,12,12,12,12,12,13,13,13,13,13,13,14,14,14,14
= 12+12/2
= 24/2
= 12

Maaf kalo salah
