Comparison of means. 来自 NCBI 喜欢 0 阅读量: 42 作者: N Berman 摘要: This chapter describes statistical methods to test for differences between means or other measures of central tendency of 2 or more populations. Parametric tests and nonparametric tests are included. Methods for pairwise ...
If a global test is not performed,multiple tests between different pairs of means will alter the alpha level, not for each comparisonbut for the experimentationas a whole. For example, if four drug levels with their six possiblecombinations are to be compared, and each comparison is made ...
aThe means of multiple groups were compared with one-way ANOVA, after the equal check of variance, and the two–two comparisons among the means were performed using the LSD method. Statistical comparison was also performed with two-tailed t-test when appropriate. P<0.05 was considered as ...
Means and standard deviations of all measurements were obtained. A t-test for paired samples was applied to identify statistical significance. The significance threshold was set at p ≤ 0.05. Since the data sets are approximately normally distributed, further statistical investigations are not ...
