Subject:      Difference between 2 correlation coefficients
Content-Type: text/plain; charset=US-ASCII

Hi,

I am analyzing data concerning the differences in strength between people
with and without difficulties preforming certain tasks. A correlation
coefficients from the entire group were high and significant. Now I wanted
to see the correlations between strength and performance within each group
i.e. the able and unable and I found that the correlation is higher within
the unable group. Is there a way for me to show that the difference in r is
statistically significant (or not)?

Thanks

Moshe
