saya butuh cara + jawabannya please..

jawab

n(s) = 40
frekuensi bentuk % diubah ke angka
f1= 7,5%  x 40 = 3
f2 = 12,5% x 40 = 5
f3 = 15% x 40 = 6
f4 = 15% x 40 = 6
f5 = 25% x 40 = 10
f6 = 12,5 % x 40 = 5
f7 = 12,5% x 40 = 5

nilai : 4,5,6,7,8,9,10
frek : 3,5,6,6,10,5,5 = 40

median data ke  1/2 (40+1) =  data ke 20,5
median = 1/2 ( data ke 20 + data ke 21)
median = 1/2 (6+7)
Median = 6,5
