Research and Analysis about Study Time using R MIYOSHI Yoshihiko In Saitama W. J. College, we have implemented many surveys which are the freshman questionnaire, the graduate satisfaction questionnaire, the class questionnaire and so on. And we summarize and report about them. The reports were only summaries of the results and has not been the statistical analysis. So as one of the attempt, I do statistical analysis using statistical analysis software R, which is freeware. In this paper, I analyzed the questionnaire about study time. 1 R 1 R 201410313.1.2 2 SASSPSSStataJMP R R Windows 3264 Linux MaxOS X
