1. ### How to do ANOVA (or similar) analysis when there are multiple groups?

Thanks for advice - I'll give this a go and see if I get different results to the original analysis (which for the life of me I can't quite figure out how I did!)
2. ### How to do ANOVA (or similar) analysis when there are multiple groups?

I mean that it's likely that some regions will have different velocities overall in group A vs group B, and I want to find those differences. Regions 1-4 are regions of interest (where a difference between groups A and B might exist if our hypothesis is correct) Region 5 is a "control" region...
3. ### How to do ANOVA (or similar) analysis when there are multiple groups?

I have 40 patients I have made some measurements in. 20 have a disease (group A), and 20 are reference/control patients (group B) The measurements I've taken are the conduction velocity of electrical impulses in various regions of the patients' hearts. Let's call them regions 1-5. I want to...
4. ### Calculating a weighted mean/SD of x number of means/SDs?

Sorry, all I’m trying to say is that for some of the mean/SD values, the number of points used to obtain those values is 40, for other values it’s 17. Each of the 10 means/SD has a different number of points used to calculate them. I need to subsequently calculate the man of all the means and an...
5. ### Calculating a weighted mean/SD of x number of means/SDs?

I'm doing some data analysis of patients undergoing cardiac ablation procedures. We use our equipment to collect electrical data from inside patients' hearts in quite high resolution. I'm struggling to see if the following can be done: I have 10 patients. We have some proprietary software that...
6. ### Basic question: How to analyse baseline characteristics for study (GraphPad Prism)

Hi I do apologise for the basic question here, but I am very new to this. I'm trying to report my baseline characteristics for a clinical pilot study we performed. I have three experimental groups and would like to report the following table as you would find in a clinical trial paper, but...
7. ### Test for independent associations between patient characteristics and events

So sample size about 80. I'm aware it's quite small and will likely result in mostly non-sig results but needs to be done! Many thanks for that! Just waiting for a few additions to the data and then can get started on your suggestions. I'm sure I will end up needing more help with stuff I don't...
8. ### Test for independent associations between patient characteristics and events

Hi, Recent new member here. Have already learned some really useful things from this forum by searching through old threads, so I'm glad I stumbled across this site! I have a question of my own that I was hoping to get some help with. We've run a clinical study. Prospective observational study...
