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.
