鉴于假设检验在统计推断中的重要地位和学习它的困难度,通过讨论两类错误的产生与控制,结合概率论中的＂小概率原理＂和逻辑方法中的＂反证法＂,给出了一种清晰简便的假设检验推导和推理方法。该方法适用于一个总体下总体均值、总体比例、总体方差的检验,也适用于两个个总体下总体均值、总体比例、总体方差的检验。检验结果表明,该推理方法简便、自然、适宜推广。
鑒于假設檢驗在統計推斷中的重要地位和學習它的睏難度,通過討論兩類錯誤的產生與控製,結閤概率論中的＂小概率原理＂和邏輯方法中的＂反證法＂,給齣瞭一種清晰簡便的假設檢驗推導和推理方法。該方法適用于一箇總體下總體均值、總體比例、總體方差的檢驗,也適用于兩箇箇總體下總體均值、總體比例、總體方差的檢驗。檢驗結果錶明,該推理方法簡便、自然、適宜推廣。

In view of hypothesis testing plays an important role in statistical inference and learning hypothesis testing extremely difficult,By discussing two types of errors to produce and control two types of errors,combined with probability theory of the"small probability theory" and logic approach of the "reductio ad absurdum",given a clear and simple method of hypothesis testing Deduction and reasoning.The method is suitable for the inspection of an overall population mean,the overall proportion of the population variance,also applies to the next two months the overall population mean,the overall proportion of the overall variance of the test.The test results show that the reasoning method is simple,natural,suitable for promotion.
