First of all, THANK you very much for everyone's responses.
Secondly, yes, an N of 7 is sparse. The 0 means no observations. I'm
hesitant to remove St1 because of the already small sample size, even though
it lacks . I oriented the data vertically as in my first scenario and ran
nonparametric stats comparing AN with HA. The scatter plot showed a
monotonic relationship , so I ran Spearmans rho. I thought the higher
specificity of Kendall's Tau would be useful, because of its accuracy over
Spearman with smaller sample sizes. I also ran Somer's d, since I have
dependent and independent variables. All showed positive correlations at
.001. However, I'm worried that I'm missing something more essential with my
data or that I've missed assumptions that made these metrics inappropriate
to begin with. From your responses, I'm even more nervous.
Thank you again for the interest in my situation and your helpful insights.
I wish my committee and those I approached for participation were as engaged
as you are.
