Answer 1

Verified answer

A. Mean

Mean = (28.7 + 30.13 + 31.10 + 32.7 + 34.5 + 35.8) / (7+13+10+7+5+8)
Mean = (196 + 390 + 310 + 224 + 170 + 280) / 50
Mean = 1570/50
Mean = 31,4 kg

B. Modus

Modus = 30

karena berat badan 30 kg paling banyak yaitu 13 siswa

C. Median

n = 50

- n/2 = 50/2 = 25
- n/2 + 1 = 25 + 1 = 26

Lokasi Median = 1/2 (25 + 26)
Lokasi Median = 1/2 . 51
Lokasi Median = 25,5 kg

Berarti median ada di antara data ke 25 dan 26.

Median = 1/2 . (50/2 + 51/2)
Media = 1/2 . (25 + 25,5)
Median = 1/2 . 50,5
Median = 25,25

Mohon maaf apabila ada yg salah

Semoga membantu dan semoga bermanfaat...
