Diketahui :
> B. indonesia = 70
> Matematika = 68
> PPKN = 100
> IPS = 55
> IPA = 67
> B. Inggris = 88
> TIK = 90
Ditanya :
Mean/ rata-rata data
Jawab :
Rata-rata = jumlah seluruh data : banyak data
= (70 + 68 + 100 + 55 + 67 + 88 + 90) : 7
= 538 : 7
= 76, 8
Jadi, rata-rata/ mean data adalah 76,8
B.Indonesia = 70
Matematika = 68
Ppkn = 100
IPS = 55
IPA = 67
B.Inggris = 88
TIK = 90
---
= (70 + 68 + 100 + 55 + 67 + 88 + 90)/7
= (138 + 155 + 155 + 90)/7
= (293 + 245)/7
= 538/7
= 76,8571
