Hi Sneaks, has your supervisor asked you to clarify the number or degrees of freedom? Usually in stats the 'effect size' can be a combination of the p value, the test (r) value and the sample number taken into account ie n or d.f. For example, if you have r=0.8 and p=0.001 but the sample was only 4, it wouldn't be an effective stats result but if the sample size was 200 and this was your stats output it would be very 'effective'.
Of course I may be completely talking rubbish.............:$
I think I need to do this, but I have different df in each cell, so exploring the use of 'harmonic mean' if anyone has any clue on that please let me know!
