Differentiation of Concept of Statistics in Scientific Research of Physical Education

结合体育科研中经常产生疑问的9对统计学概念进行列举辩析,旨在提高体育科研的定量化水平。这9对统计学概念是:信度与效度、变量层次与数学模型、参数检验与非参数检验、均数的假设检验与标准差的假设检验、假设检验与方差分析、单侧检验与双侧检验、有显著性差异与无显著性差异、相关系数的显著性水平与相关的密切程度、统计学与体育学。

Combined with 9 concepts of statistics in scientific research of physical education which are usually doubted, they were analyzed in order to develop the quantified level of scientific research of physical education. They are: credit and efficiency, level of variable and mathematical model, parametric test and nonparametric test, hypothesis test of mean and standard deviation, hypothesis test and analysis of variance, significant difference and non-significant difference, level of significance of correlation coefficient and osculation degree of correlation, statistics and physical education.
