研究采用实验及统计分析法,对山西大学体育学院2002级100名男生的简单反应时分别进行10次测量;使Excel-2000软件单因素方差分析法对测量结果的可靠性进行统计分析和比较研究。在研究中,将测量次数定为10次,是为了达到简化测量方法的目的。结果表明:测量结果的取值方法不同,反应时的可靠性有显著差异。取平均值时,红光、绿先、声音分别测量10次,并且在剔除3个最大值和3个最小值后,可靠性都达到0.93以上。这种取值方法,既可以保持经济性,同时也可以保证较高听可靠性。它与目前国民体质监测工作特点是相符的。
In this study, the experiment and statistical analysis were used to measure 10 simple reactions of 100 boys in 2002 grade in Shanxi University of Physical Education respectively. Statistical analysis and comparison of the reliability of measurement results were made by Excel-2000 software one-way ANOVA . In the study, the number of measurements set to 10 times, in order to achieve the purpose of simplifying the measurement method. The results show that there are significant differences in the values of the measurement results and the reliability of the reaction. When averaging, the red light, green first, the sound were measured 10 times, respectively, and after removing the three maximum and three minimum, the reliability reached more than 0.93. This method of valuation, both to maintain the economy, but also to ensure high reliability. It is consistent with the current national constitutional monitoring.
