在解释实验数据时，必须考虑样本量和概率值。组成员和因变量之间的相关性明确地描述了自变量的有效性。提供了一个表，其中给出了直接从样本量和t， z， F或X2值度量的值。在平均数之间的差异和错误分类的度量方面，提供了这一度量的等价物。该表格适合作为权力表，并适用于处理实验程序和战术的若干问题。有关接受零假设或替代假设的决定可以通过使用此度量来辅助。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Sample size and probability values must be involved in the interpretation of experimental data. A correlation between group membership and the dependent variable explicitly describes the effectiveness of the independent variable. A table is provided which gives values of this measure directly from the sample size and t, z, F, or X2 values. Equivalents of this measure are provided both in terms of the difference between means and a measure of misclassification. The table is suitable as a power table and for dealing with several problems of experimental procedure and tactics. Decisions concerning acceptance of null or alternative hypotheses may be aided by the use of this measure.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
