差数显著性t检验与元分析的对比研究

利用计算机构造被试总体、模拟实验研究程序进行抽样研究，探讨显著性ｔ检验方法与元分析方法在检验实验结果数据方面的差异。在模拟实验过程中，ｔ验受到显著性水平、样本容量和总体效果大小的影响，因此最终影响了统计推断的可靠性，建议：在进行显著性检验过程中，应对统计检验能力进行估计；元分析方法以样本为元素对总体进行推断，因此具有很高的准确性和可靠性，它将很有可能成为今后心理学研究的重要统计工具。

A COMPARATIVE STUDY OF SIGNIFICANCE T-TEST AND META-ANALYSIS

A sampled study through computer constructed population subject group and simulated experimental study procedures probed into the difference between significance t-test and meta-analysis in testing data rusults of experiments. In the process of simulated experiment, the t-test result was affected by significance level, sample capacity and population effect size. Thus reliability of statistical inferences was affected. Suggestions: In the process of significance test, statistical testing power should be estimated; inferring population subject group througlt samples as factors, meta-analysis has high accuracy and reliability, it will very likely be a very important statistical method in later research in psychological science.
