Tentukan Mean,Modus,Median Dalam Soal Berikut. Tolong bantu Jawab

1. Median = 10 19 25 27 35 36 38 40 46 49 53

Median ( Tengah ) = 36

2. Median = 114 129 131 132 150 158 167 194 203 212

Median ( Tengah ) = 150 + 158 = 308 = 308/2 = 154.Jadi Median = 154

3.Mean ( Rata - Rata )
40 x 1 = 40
50 x 2 = 100
60 x 10 = 600
70 x 8 = 560
80 x 7 = 560
90 x 4 = 360

= 40 + 100 + 600 + 560 + 560 + 360 = 2.220

Rumus Mean = Nilai / Frekuensi =

Frekuensi = 1 + 2 + 10 + 8 + 7 + 4 = 32

Rata - Rata = 2.220 / 32 = 69,375
