Tolong jawab no 1-3 pake caranya

Mean =
jumlah semua angka : banyak angka

Median =
Angka tengah

Modus =
Angka yang sering muncul

1 . ( 6 , 4 , 5 , 6 , 3 , 8 , 7)

Mean = (6+4+5+6+3+8+7) : 7

= 39 : 7
= 5,571

Median = 3 , 4 , 5 , 6 , 6 , 7 , 8

= 6

Modus = 6

2 . ( 9 , 4 , 8 , 6 , 9 , 5 , 7 , 3)

Mean = (9+4+8+6+9+5+7+3) : 8

= 51 : 8
= 6,375

Median = 3 , 4 , 5 , 6 , 7 , 8 , 9 , 9

= (6 + 7) : 2
= 13 : 2
= 6,5

Modus = 9

3 . (6,6,7,7,7,7,7,7,8,8,8,8,8,8,8,9,9,9,9,9,9,9,9,9,9,10,10,10,10,10)

Mean = (6×2+7×6+8×7+9×10+10×5) : 30

= 250 : 30
= 8,33

Median = 6,6,7,7,7,7,7,7,8,8,8,8,8,8,8,9,9,9,9,9,9,9,9,9,9,10,10,10,10,10

= (8 + 9) : 2
= 17 : 2
= 8,5

Modus = 9

Sekian dari saya
Maaf jika salah
