This paper presents a look at the underused procedure of testing for Type II errors when "negative" results are encountered during research. It recommends setting a statistical alternative hypothesis based on anthropologically derived information and calculating the probability of committing this type of error. In this manner, the process is similar to that used for testing Type I errors, which is clarified by examples from the literature. It is hoped that researchers will use the information presented here as a means of attaching levels of probability to acceptance of null hypotheses.
本文探讨了在研究中遇到“阴性”结果时未充分利用的II型错误检验程序。它建议根据人类学得出的信息设定一个统计备择假设，并计算犯此类错误的概率。通过文献中的例子可以看出，这种方式与用于检验I型错误的过程类似。希望研究人员能将此处提供的信息作为一种手段，为接受原假设赋予概率水平。
