I'm trying to report the results of some ANCOVAs I have run in SPSS. The only problem is that I can't figure out which degrees of freedom are within groups and between groups (in APA format you report (F(dfbetween,dfwithin). DF are listed for the following variables: corrected model, intercept, BMI (my covariate), Eth_Recode (my IV), error, total, and corrected total. Which is which? Thanks in advance.
