心理统计中关于标准差的转化问题研究

Study on the Problem of the Conversion of the Standard Deviation in Psych-statistics

标准差是心理实验中数据处理常见的重要统计量。常见的四个标准差有着严格的定义和特定的使用条件,它们之间有着特殊的转化关系。据此可简化假设检验过程,提高统计推断的准确性．

Standard deviation is the most valued statistics in the experiment of psychology. We usually get four kinds of standard deviations which have the strict definitions and must be used under different conditions, These four standard deviations may convert to each other,so that it can simplify the process of hypothesis testing and highly improve the accuracy of inferential statistics.
