    Hi,

    So we've always been told that the degrees of freedom is n-1, however for some tests (on SPSS) it tells you the df and it just says the sample size rather than n-1 (for instance on the Shapiro-Wilk test of normality). Now I've done two correlations (a pearson and a spearman's rank) and need to report the df but I don't know whether to write it as the sample size or n-1, I don't know how you tell which one it is.

    Any help appreciated, thanks!

    I'm pretty sure df is always n-1 regardless of what SPSS says.
