Based on multiple linear regression analysis of ability of medical postgraduate students to express SPSS experiment results with three-line table

Abstract

Abstract Medical postgraduate students (MPS) can select the appropriate statistical methods to do the SPSS experiments and view the experimental results after they have taken SPSS course. It is vital for MPS to exactly convert SPSS experiment results into three-line table in their academic papers. This paper investigated the Ability of MPS in Expressing SPSS experiment Results with Three-Line Table (AERTLT). The enrolled MPS in Southwest Medical University filled in the questionnaire about AERTLT on Jan, 2019. Questionnaire data are analysed using Multiple Linear Regression (MLR). Complex decision factor R 2=0.834254 and adjoint probability p<0.001 in MLR suggest the linear correlation between AERTLT and 16 factors passes test. Then backward deletion variable method is employed to repeatedly delete the factor whose coefficient is the minimum value in partial f-test. AERTLT can be expressed by four significant factors i.e. “Analytical results in comparison of mean and population mean”, “Analytical results in regression analysis”, “Comment description in three-line table”, and “P-Error in insufficient sample size or unsatisfactory univariate analysis”. These four factors are the key point for SPSS course to cultivate MPS in the medical universities and colleges.
