Answer 1

Jawaban:

2) nilai = 75, 67, 83, 95, 77, 92, 68, 87

frekuensi = 8

rata² = jumlah data / frekuensi

rata² = (75 + 67 + 83 + 95 + 77 + 92 + 68 + 87) / 8

rata² = 644 : 8

rata² = 80,5

3) nilai = 85, 87, 84, 76, 90, 86, 90, 88

frekuensi = 8

rata² = jumlah data / frekuensi

rata² = (85 + 87 + 84 + 76 + 90 + 86 + 90 + 88) / 8

rata² = 686 : 8

rata² = 85,75
