摘要
在量化研究中,研究者通常从特定的研究假设出发,通过对抽象概念的操作化定义确定变量,并运用问卷、量表、结构式访谈与观察等方法收集资料,然后进行统计分析来检验研究假设。本文旨在探讨量化研究的本体论前提,并从认识论和方法论视角分析量化研究中的可靠性和有效性问题。
In quantitative research, researchers usually start from a specific hypothesis, determine variables by the operational definitions of the abstract concepts, collect data by means of questionnaires, scales, structural interviews, and observations, and then test those hypotheses by statistical analysis. This paper aims to inquire into the ontological precondition of quantitative research and to analyze the issues of reliability and validity in quantitative research from the perspectives of epistemology and methodology.
