【摘要】:正概率抽样(probability sampling):也称"随机抽样"(random sampling)。其特点是每个被抽取的个体都有相同的机会被抽中。具体的概率抽样方法包括简单随机抽样、分层抽样、集束抽样和系统抽样。非概率抽样(non-probability sampling):也称"非随机抽样"或"不等概率抽样",指没有采用随机抽样方法而选取样本的方法。
[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.
