60,75,65,82,85,75,91,85,75,82 cari mean and median

kita urutkan dulu.
60, 65, 75, 75, 75, 82, 82, 85, 85, 91

Mean = Nilai rata-rata =>
Jumlah seluruhnya ÷ frekuensi
(60 × 1 ) + (65 × 1) + (75 × 3) + (82 × 2) + (85 × 2) + (91 × 1) =
(60) + (65) + (225) + (164) + (170) + (91) =
775 ÷ 10 = 77,5

Median = Nilai tengah
(75 + 82) ÷ 2 = 157 ÷ 2 = 78,5

#SemogaMembantu^^
#JanganLupaTerimaKasih<3

Mean = nilai rata rata
60 +75 + 65 + 82 + 85 + 75 + 91 + 85 + 75 + 82 = 775/10 = 77.5

median = nilai tengah
60, 65, 75, 75, 75, 82, 82, 85, 85, 91

75 + 82 = 157/2 =78.5

semoga membantu :D
