最近我需要比较健康人和病人之间6个指标的differences, 而这6个指标 A, B, C, D, E, F, 之间有某些关系,也就是说,
每个指标都是由不同的3个元素 alpha, beta, gamma 排列组合而成的
如附图所示, 如果我想比较健康人 (n=4) 和病人 (n=7) 之间. 在这6个指标 A, B, C, D, E, F 上表达的不同,
请问
1) 请问这是multiple comparisons多重比较吗?
能用Student’s t-test吗?
能用Mann–Whitney’s U-test吗?
2) 有何统计学方法的策略?
我从文献上读到如下策略, 请问可行吗?
The χ2 goodness-of-fit test 用来评估 normality for all parameters.
The F-test and Bartlett test 用来评估 equality of variance between two and three groups,
For multiple comparisons多重比较, the two-factor analysis of variance and Scheffe’s F tests were used when
data were normally distributed and the variance was equal,
而 Friedman and Scheffe’s F tests were used when the data were not normally distributed or the variance
was not equal.
3) 请问有何统计软件推荐? SPSS 还是 GraphPad? 如果是前者, 请问第几版合适? 中文版可以吗?
非常感谢
