multiple comparison

1. Can I make a comparison among groups which the control group's data was set to be 100%?

Hello I want to make a comparison between the groups. However, in the control group, all of the data was set to be 100% and the data of the other groups is the proportion compared to the control group. So the data will look like, (just for example) control group: 100%, 100%, 100%, 100%, 100%...
2. Can I use ANOV for testing how correlation coefficient varies in condition??

Hi everyone, I have a problem with the statistical analysis of my data namely I want to look into how anatomical values correlate with some electrophysiological ones, in different condition. Trying to simplify and explain, I want to relate the volume of some brain structures (a, b, c) to an...
3. One Way ANOVA/Post Hoc with Time as Independent Variable

I've been working on replicating/updating an old analysis on student test scores that doesn't have a very helpful methodology section. I've spent a number of days searching online for a similar situation so I can see if what I'm doing makes sense with no luck. I would greatly appreciate any...
4. Multiple MANOVAs - How to adjust post-hoc ANOVA p-values

Hi everyone I have (multiple) dependent variables which I split into two groups. For each group I do a separate MANOVA (one group for metabolism-related genes and one group for immunity-related genes). I assume that if I do post-hoc ANOVAs for each dependent variable (i.e. gene), I will...
5. Is multiple comparison correction analysis applicable? If yes, which one?

Hello, I am doing simple linear regressions between a number of ecological variables and 10 different landform parameters. For each ecological variable, I am looking for which of the landform parameters show significant (o.05) relationships. As I am looking at 10 regression results (one...
6. Multiple comparison problem (one-to-many)-Protein sequence

Dear All, I am new here and this is my first post. I have a problem where I am comparing a set of 9 protein amino acid (AA) sequences (Proteins I am interested in) vs 1000 random of proteins sequence sets 9 by 9. Basically, I am trying to confirm that some AA (e.g. Alanine) are enriched in my...
7. multiple comparison of chi square tests of binary data

Hello everybody, the code below is to illustrate how I examined the (significant) differences in certain characteristics between different regions. The data set is non-parametric so I used the Kruskal Wallis test and for multiple comparison between the regions I used the function kruskalmc. I...
8. p-value associated with Kruskal Wallis with multiple comparison?

I have a data set that shows the differences between 3 different controllers of a biomechanical system on the same performance metric (specifically, I measure each controller's performance on a set of N tasks, and record the percentage of tasks that achieve success (i.e. the controlled segment...
