Statistika

Penjelasan dengan langkah-langkah:

1. Data : 4, 5, 6, 7, 7, 8, 8, 8, 8, 9, 9, 10, 11, 12, 13

n. Data = 15

Total = 125

Mean = 125/15 = 8,33

Modus = 8 (sebanyak 4 kali)

Median = 8

2. Frekuensi = 33

   Total = 3 + 12 + 25 + 48 + 49 + 40 + 27 + 10 = 214

Mean = 214 / 33 = 6,48

Modus = 6 (Sebanyak 8 kali)

Median = data ( (33 + 1)/ 2) = data ke 17 = 6

1. Data = 4,5,6,7,7,8,8,8,8,9,9,10,11,12,13

Mean = Jumlah/15 = 125/15 = 8,3

Modus = 8

Median = 8

2. Data = 3,4,4,4,5,5,5,5,5,6,6,6,6,6,6,6,6,7,7,7,7,7,7,7,8,8,8,8,8,9,9,9,10

Mean = Jumlah/33 = 214/33 = 6,4

Modus = 6

Median = 6
