Re: PSPP - calculate effect size (Organisation CIT)

[Dr. Oliver Walter]

Dear Ms Lindner,

your question about the possibility to calculate "the effect size" is a bit 
difficult to answer because there is a variety of effect size measures in 
the literature. Among them you can find the correlation coefficient r which 
is, of course, computable by using PSPP. It is possible to calculate Cohen's 
d from the correlation coefficient r as it is possible to calculate other 
effect size measures from other statistics computed by PSPP. But as far as I 
know effect sizes measures such as Cohen's d or (partial) eta squared are 
not directly computed by PSPP (except other coefficients of correlation and 
contingency).

Sincerely,

Oliver Walter
