统计意义是指研究结果是由于偶然还是抽样的可变性；实际意义是指研究结果在现实世界中是否有用。随着人们对零假设显着性检验的局限性的日益认识，人们开始寻找补充这些方法的方法。已经提出了各种影响程度的补充措施。这些程序的使用在四个APA期刊中进行了审查，并描述了一种评估数据实际意义的方法。
Statistical significance is concerned with whether a research result is due to chance or sampling variability; practical significance is concerned with whether the result is useful in the real world. A growing awareness of the limitations of null hypothesis significance tests has led to a search for ways to supplement these procedures. A variety of supplementary measures of effect magnitude have been proposed. The use of these procedures in four APA journals is examined, and an approach to assessing the practical significance of data is described.
