多组比较,也就是两组以上的比较。事实上,多组是包含两组的,或者说,两组比较只是多组比较的一个特例。虽然仅仅是多了一个或几个组别,但多组定量资料的组间比较却比两组比较要复杂的多。不管是在概念上还是内容上,多组比较都要更加丰富。本文主要介绍多组定量资料比较中的一些常用方法及分析策略,并对论文中常见的一些错误进行分析。1多组定量资料比较的常用分析方法多组定量资料的比较,其方法选择与两组比较 Multi-group comparison, that is, more than two groups of comparison. In fact, a multi-group contains two groups, or two groups of comparison is only a special case of multi-group comparison. Although only one or a few more groups were included, the comparisons of multiple sets of quantitative data were much more complicated than the two groups. Whether in concept or content, multiple sets of comparison should be more abundant. This article mainly introduces some common methods and analysis strategies in the comparison of multiple groups of quantitative data, and analyzes some common mistakes in the thesis. A group of quantitative analysis of more than one commonly used method of quantitative analysis of multiple sets of data comparison, the method of choice compared with the two groups
