传统统计方法面临的挑战:元分析方法

利用计算机构造实验组和控制组总体，进行传统统计方法与元分析比较实验研究。在实验组总体高出控制组总体０．５０个标准差的提下，传统ｔ检验的统计检验能力（Ｐ）仅为为４１％；而利用元分析的方法进行统计分析，其结果与计算机构造模型有很高的一致性从而提出元分析方法在进入心理学实验研究和证实理论方面的有效性和可靠性，以及传统统计方法面临挑战的事实。

A CHALLENGE THAT TRADITIONAL STATISTICAL METHODS IS FACING: META-ANALYSIS

Traditional statistics methods and meta-analysis were compared in both experi-mental and overall control groups in our experimental study using computerconstruction. Under the condition of 0.50 standard diviation higher in the overall ex-perimental group than in the overall control group, the satistics testing power of thetraditional t testing was only 41%; while using meta-analysis method to analyse sta-tistics, the result was highly consistent with computer construction model. Thus it wassuggested that meta-analysis method had its validity and reliagility in psychologicalexperimental study and proving theories as well as the reality of a challenge thattraditional statistics method faces.
