This paper deals with the null distribution of one-way ANOVA test statistic T for testing the equality of means of q nonnormal populations with unequa variances. In thwis situation , there are several test statistics Specially, we consider just this one which has been proposed by James(1951)...
What is ANOVA in statistics? For a one-way ANOVA test, the overall ANOVA null hypothesis is that the mean responses are equal for all treatments. The ANOVA p-value comes from an F-test. Can I do ANOVA in R? While Prism makes ANOVA much more straightforward, you can use open-source ...

To see an alternative to traditional hypothesis testing that does not use probability distributions and test statistics, learn aboutbootstrapping in statistics! Note: I wrote a different version of this post that appeared elsewhere. I’ve completely rewritten and updated it for my blog site. ...
以下笔记来源于《Statistics for the Behavioral Sciences 10e》 Analysis of variance (ANOVA) is a hypothesis-testing procedure that is used to evaluate mean differences between two or more treatments (or populations). It may appear that ANOVA and t tests are simply two different ways of doing exac...
