Nonrandom sampling methods usually do not produce samples that are representative of the general population from which they are drawn. The greatest error occurs when the surveyor attempts to generalize the results of the sur是什么意思？ 待解決

這是一個非隨機抽樣簡單，有點荒謬，例如。但是，它使點。非隨機抽樣方法通常不產生代表一般人群，從他們繪制的樣本。最大的錯誤發生時，驗船師試圖概括整個人口從樣品中獲得的調查結果。這樣的錯誤是陰險的，因為它不是在所有明顯從單純的數據看，或什至看樣品。確認樣品是否具有代表性與否的最簡單的方法是，以確定是否被抽選隨機。是一個隨機抽樣的方法，必須滿足兩個條件。如果兩者都滿足，由此產生的樣本是隨機的。如果不是，它是一個非隨機抽樣技術：
