1目的 了解医学院校学报论著统计分析方法的应用状况及存在的问题。 2方法 调查了山东省 6所医学院校学报 1992年及 1997年的论著分别为 44 4,5 2 4篇。 3结果 1997年论著中的统计方法使用率为6 4.31% ,1992年为 5 2 .93% ,1997年高于 1992年 ,差异有显著性 (χ2 =12 .89,P<0 .0 1)。常用的方法是 t检验、χ2检验、相关分析和方差分析 ;较常见的统计问题有 :只写 P值而未注明所用统计学方法 ,用 t检验代替方差分析进行多组均数间的比较 ,等级资料比较用χ2 检验等。 4结论 1997年论著的统计使用率高于 1992年 ,但仍存在复杂方法使用率低及误用率高等问题 ,有待于进一步提高
1 Objective To understand the application status and existing problems of statistical analysis methods in medical college journals. 2 Methods The papers of 6 medical colleges in Shandong Province in 1992 and 1997 were investigated 44 4, 524 articles respectively. 3 Results The utilization rate of the statistical methods in the works of 1997 was 6 4.31%, which was 52.93% in 1992 and higher than that in 1992. The difference was significant (χ 2 =12.89, P<0.01). . The commonly used methods are t-test, χ2 test, correlation analysis, and analysis of variance; the more common statistical problems are: writing P value without indicating the statistical method used, and using t-test instead of variance analysis to compare multiple groups of means. , grade data comparison using χ2 test and so on. 4 Conclusions In 1997, the statistical usage rate was higher than that in 1992, but there are still problems such as low utilization rate and high misuse rate of complex methods, which need to be further improved.
