统计抽样的思想方法是以假设检验为前提,设定抽样参数,确定抽样规模,无人为偏见的随机抽取样本进行审核,根据需要扩大样本,逐次逼近总体特征,根据样本特征经科学计算推导,得出总体结论

結果 (英文) 1:

Statistical sampling methods was premised on hypothesis testing, set the sampling parameters to determine the sample size, no biased random samples for review, according to the need to expand the sample and successive approximation properties of sample characteristics after scientific calculation, drawing some general conclusions

結果 (英文) 2:

Statistical sampling method is based on the idea of ​​hypothesis testing as a precondition, set the sampling parameters, determining sample size, no review of randomly selected sample bias, according to the need to expand the sample, the general characteristics of successive approximation, based on sample characteristics are derived by computing science, too the overall conclusions

結果 (英文) 3:

Thought of a statistical sampling method is based on the assumption that the test is the premise of setting sampling parameters, sample size determination, examine the random samples without prejudice, according to the need to expand the sample, the successive approximation is derived according to the general characteristics, calculation of sample characteristics of the science, the total conclusion
