Hi, I have difficulties using SPSS for my study, I'm not entirely sure which analysis to make. I'm trying to compare the velocity of sneezes between groups (neuro disorder + non-neuro). e.g. I'm having 15 participants with results ranging from 0.1 to 0.6 and a control group of 15 people with results ranging from slightly faster results.
My question is how to I properly set these up? I've been trying to use the Mann-Whitney approach but I cannot seem to get any answer out of it. I think my problem is that I'm just terrible at using the program, trying to make two different variables that I'm trying to run against each other.
I often get the "not enough valid cases" - error message. What's up?
I've been trying to use Youtube for help, but there are no youtube-videos of a similar problem? So I have Group A, 15 different results, ranging from 0.1 - 0.6, and a control group ranging 0.02 - 0.3, and a different parameter (age) which I'd like to also run into the mix. How do I set this up?
I'm dumb. /JP
