【摘要】：正概率抽樣(probability sampling):也稱"隨機(jī)抽樣"(random sampling)。其特點是每個被抽取的個體都有相同的機(jī)會被抽中。具體的概率抽樣方法包括簡單隨機(jī)抽樣、分層抽樣、集束抽樣和系統(tǒng)抽樣。非概率抽樣(non-probability sampling):也稱"非隨機(jī)抽樣"或"不等概率抽樣",指沒有采用隨機(jī)抽樣方法而選取樣本的方法。
[Abstract]:Positive probability sampling (probability sampling):, also known as "random sampling" (random sampling). The feature is that each individual being drawn has the same chance of being drawn. Specific probability sampling methods include simple random sampling, stratified sampling, cluster sampling and systematic sampling. Non-probabilistic sampling (non-probability sampling):), also known as "non-random sampling" or "unequal probability sampling", refers to the method of selecting samples without random sampling.
