    Multiple comparisons to a reference value - which test?

    That is right. But it also means that I might dismiss results because of this. I know, for example, that one always should formulate a hypothesis before applying statistics and not afterwards. But what do you mean by the above sentence? When doing multiple comparison tests, I select one from...

    Multiple comparisons to a reference value - which test?

    I understand. Thanks for your answer. Bonferroni is quite conservative when lots of comparisons are made. I know several other multiple comparison tests but I don't know which adjustment/correction can also relatively easily be performed with Microsoft Excel. Is there any less conservative...

    Multiple comparisons to a reference value - which test?

    Hi, if I wanted to compare a sample to a fixed reference value, I would use the one-sample t-test (or the nonparametric one-sample Wilcoxon signed-rank test). However, I don't know which test I should use if I want to compare several different samples to that single reference value. Dunnet's...

    Two-way ANOVA or one-way ANOVA for time-course experiment with different drugs?

    @GretaGarbo: Thanks for the link. Actually, it is a combination of the two examples given on the first page of your website link. There are different time points as in the first example and there are different treatments as in the second example. The experimental design is definitely a repeated...

    Two-way ANOVA or one-way ANOVA for time-course experiment with different drugs?

    Can you explain to me why you think so? I mean testing for factor interactions is not of interest here, which is one of the questions to be answered by a two-way ANOVA, and neither is the time course.

    Two-way ANOVA or one-way ANOVA for time-course experiment with different drugs?

    Hi, I am not sure which statistical procedure can and has to be applied here. First, I will try to explain the experimental setup resulting in the data to be analyzed statistically. The data are levels of the cytokine IL-6 in the blood of mice treated with three different drugs and of...
