摘要
本文结合教育与心理学的实验用数理统计的理论,探讨Ⅰ型错误的概率α与Ⅱ型错误的概率β之间的反比关系以及Ⅰ型错误、Ⅱ型错误与样本容量的关系。指出在教育与心理学的实验研究中对它们慎重考虑的必要性。
Combining the experiment of education and psychology ith statistica theory, this paper probes into the inverse relation of probability of Type Ⅰ error to probability of Type Ⅱ error, as well as the relation of sample size to Type Ⅰ error and Type Ⅱ error. It points out that in the experiment research of education and psychology, these relations have to be handled with great care.
