Jawab:
a. Mean
Mean = total nilai / total siswa
Mean = 196 / 27
Mean = 7.2593
b. Median
Median = ( data n/2 + data n/2 +1) / 2 --- data genap
= (data (n+1)/2) ---- data ganjil
Karena diketahui n=27
median = data (27+1)/2
median = data ke 14 => 7
c. Modus
Modus => data yang paling sering muncul (frekuensi terbesar)
modus data = 8 (frekuensi 8)
