体育测量可靠性的概念及评估方法分析

运用文献资料法,分析了体育测量可靠性的概念和评估方法,指出了当前存在的问题,主要结论为:体育测量可靠性的理论基石是经典测量理论;测量可靠性就是测量信度,是测量结果的一致性和稳定性;测量可靠性的定义式r=1-S~2_E/S~2 _X只有理论价值,一般不可用来进行可靠性系数的计算;以平行测量之间的相关性来评估体育测量的可靠性是目前最为可行的方法,但此法也存在一定的局限性;应用"信度"取代"可靠性"作为体育测量术语.

The Principle and the Method of the Survey Reliability Appraisal in Sports

Using ducument material survey,the author analyzed the concept and the appraisal method of sports survey appraisal,and pointed out the question existing Currently.The result and conclusion is:the cornerstone of sports survey reliability is Classical Test Theory;the defination of measuring:refiability is the compatibility and stability of the measure result;the definition formula r=1-s_E~2/S_x~2 only,has theoretical value,and may not be used to estimate the survey reliability generally;the most feasible method of appraising survey reliability is calculating the correlation coefficient of the the parallel survey. However,it has some limits.
