Toplam ürün sayısı=1000
Her kümedeki ürün sayısı=20
Küme sayısı= Toplam ürün sayısı/Her kümedeki ürün sayısı
Küme sayısı = 5
Yani 50 küme seçilmelidir.
Bir ürünün seçilme olasılığını bulmak için, seçilen ürünlerin üretilen toplam ürün sayısına göre oranını dikkate almamız gerekir:
Bir ürünün seçilme olasılığı Her kümedeki ürün sayısı/Toplam ürün sayısı.
Bir ürünün seçilme olasılığı 20/1000 = 0,02.
Yani bir ürünün seçilme olasılığı 0,02 yani %2'dir.
