效应量在心理及教育研究中的应用
在过去的二十年里,在社会和行为科学研究中,效应量 (Effect Size) 在实证研究中的使用和解释变得越来越重要。效应量的应用已被专业组织协会(例如,美国心理学协会,APA)提倡为良好的研究实践做法。 此外,心理学和教育领域的一些学术期刊也已有在研究报告中包括和讨论效应量的要求。 但是,许多研究者对效应量及应用缺乏足够的了解。 这次演讲将讨论效应量在实证研究中的意义和重要性,并将说明在不同分析背景下效应量的不同的呈现方式。 最后,将提供一些指导来理解和解释在实证研究中的效应量。
Use of Effect Size Measures in Psychology/Education Research
Use and interpretation of effect size in empirical studies have become more important in social and behavioral science research in the last two decades, as this has been advocated as good research practice by professional organizations (e.g., American Psychological Association, or APA). Furthermore, some prominent journals in psychology and education have made it a requirement for reporting effect size in the research findings. However, there is a lack of understanding about the current state of affairs with regard to effect size measures in different analytical contexts. In this talk, the relevance of effect size in empirical studies will be discussed, and effect size measures in different analytical contexts will be illustrated. Finally, some guidelines will be provided in understanding and interpreting effect sizes in empirical studies.
