4,4,5,5,5,6,7,8,9,x
jumlahkan semuanya...
53+x=6×10 10 itu banyaknya angka
x=60-53 6 nilai rata2(mean)
x=7
mediannya.....
(urutin lagi)
4,4,5,5,5,6,7,7,8,9
karena bilangannya genap jadi...
5+6/2=5,5
begitulah.....
6 = 53+x/ 10
60= 53 + x
x = 60 - 53
x = 7
data akhir = 4,4,5,5,5,6,7,7,8,9
median = data tengah = 5 +6 / 2 = 11/2 = 5,5
