数理统计对于教育与心理科学研究具有重要的方法学意义,由于无原始观测值的独立样本可能仅提供了样本统计量,而在进行假设检验时,检验统计量的计算复杂,而又无法根据检验统计量得到其精确累积分布概率,SPSS、SAS、Excel等也没有提供相应的功能,要想在此类软件中实现,需要有一定的编程基础,而VB是一种简单易学的语言,结合MATLAB数值计算的能力,很容易实现这一目标,本文以VB和MATLAB混合编程实现无原始观测值的两独立样本t检验。
Mathematical statistics have important methodological significance for educational and psychosocial research. Since independent samples without original observations may only provide sample statistics, the calculation of test statistic is complicated when the hypothesis test is performed, Statistics get its exact cumulative distribution probability, SPSS, SAS, Excel, etc. also did not provide the corresponding function, in order to achieve in such software, you need to have some programming foundation, and VB is an easy to learn language, combined with MATLAB The ability of numerical calculation, it is easy to achieve this goal, this article mixed programming with VB and MATLAB to achieve two independent sample t-test without original observations.
