假设检验中的P值法在实际生活中的应用摘 要假设检验是统计判断的重要内容,在很多情况下大多采用临界值法,而在现代统计软件中假设检验多是采用计算P值的方法进行推断的。检验时需要由样本观测值计算出检验统计量的观测值和衡量观测结果极端的值,然后通过比较P值和显著性水平的大小作判断,当时,拒绝原假设;当时,不能拒绝原假设。论文列举了P值检验法在生活中一些应用案例,并和临界值法的做了优势比较。关键词:假设检验;临界值法;P值法;SASThe application of Hypothesis test P-value method in real lifeAbstractHypothesis test is an important content of statistical judgment; the critical value method is used in many cases.
