摘要
变量是统计学中的一个基本范畴,但各类统计学教科书中,对变量的定义众说不一,难以体现其在统计学中的重要性。本文结合多元统计分析中变量的等级分类,给出“变量”在统计学范围内的内涵与外延解释,并且说明清晰界定“变量”对统计学教学的意义。
Variable is the basic conception in Statistics, but there is no unified definition in the corresponding textbooks which can embody it' s importance in Statistics. This article analyses the former discussion of this problem. On the basis of these, the author tries to redefine the definition of Variable in Statistics.
