<DIV><FONT face=Aharoni>I want to calculate the effect size for my chi-square
stat. findings in a comparison of the number of collocations occurring in 4
corpora standardized to 40,000 words. A significant difference was found
between the 4 groups (Chi-square (df3) = 73.39,
p<.0001). <SPAN style="FONT-FAMILY: 'Book Antiqua'">Additional
comparisons between each pair of groups revealed significant differences
between corpus 1 and 2(chi-square = 180.18, <I>p </I>< 0.001), corpus 1 and 3
(chi-square = 74.93, <I>p</I> < 0.001) and corpus 1 and 4 (chi-square 55.77,
<I>p</I> < 0.001). </SPAN></FONT></DIV>

<DIV><FONT face=Aharoni><SPAN style="FONT-FAMILY: 'Book Antiqua'">I read that
effect size is done by computing the square-root by dividing the sample size.
Does this mean I divide the sample size of the running words in the corpus? Do I
use the raw frequencies? Do I divide the number of collocations?
