摘要
在推断统计方法中,效应幅度的应用较显著性检验有较大的优势,但在国内却并未引起重视。文章整理了国内外关于t-检验效应幅度测定值的计算公式及适用条件;并对不同计算公式在t-检验效应幅度的判定结果上是否具有一致性进行了验证;再结合数据及定义分析,分别为三种t-检验效应幅度测定值的计算推荐了较合理的计算公式;最后进一步对比了显著性检验与t-检验效应幅度在外语实证研究中的应用差异。
Effect size is important as significance level in the statistical methods,but it did not cause everybody’s attention.In order to widely used of t-test’effective size in quantitative study,the author has researched three respects.First,the counting methods and application conditions of the t-test’effective size were made out.Second,whether or not consistency had been verified for the t-test’effective size with the different counting methods.The third,the more reasonable or scientific counting methods were recommended for the t-test’effective size by analyzing the data and definition.
