Which statistical test to use?
To find out which test to use, make sure you know your data
-
- independent variables (groups or conditions; what you manipulate)
- dependent variables (what you measure)
- paired/unpaired data (do the same people go through all the conditions or not?; check within vs. between-subjects design)
- level of measurement (categorial, metrical)
