Should I use One-sample t test, or Two-sample t test in SPM?
It sounds like a two-sample test (spm1d.stats.ttest2) might be appropriate. This would test the null hypothesis:
H0: (mean Task A) = (mean Task B)
If statistical analysis was used for one participant, does the analysis have meaning about statistics?
I would have statistical meaning, but that meaning would pertain to only this participant. The results would be relevant to this particular athlete, but not necessarily to anyone else.
I have some questions about One-sample t test. In the spm1D homepage, I downloaded Slides_Booklet.pdf. In the slide ‘1. One subject, multiple trials, two tasks’ was shown in the Experimental scenarios.
My current research is analyzing champion athlete data as I mentioned in another question.
The champion athlete (n=1) was participated. He did two tasks, and repeated 5 times by each task. Kinematic data were measured by motion capture system. The positions of center of mass were calculated.
I would like to compare the movement of center of mass for the champion athlete between two tasks. Should I use One-sample t test, or Two-sample t test in SPM?
