I'd like to better understand your study design (I've re-read the initial round of posts.) In your reply, you said, you observed the target kid for a total of 50 minutes. What I'm curious about is the data collection procedures used. I think these matter in understanding what your data analysis options are. The target behaviors were anxiety (Anx) and hyperactivity (HA). For example, you could have tabulated using two hand counters or hash-marks on paper each time a target behavior occurred so that at any point in time, the HA counter or hash count would show a count of 15 and the Anx counter or hash count would show a count of 8. Alternatively, you could have recorded in a data sequence the behaviors as they occurred so now the recording sheet/data recorder shows, for example, A,H,H,A,A,H,H,H. Alternatively, you could have designated HA as the stimulus behavior and Anx as the response behavior and coded (HA,Anx) if Anx followed HA within 'x' seconds; otherwise, coded (HA,NoAnx). In one of your replies, you mentioned something about 30 seconds. What's the story with that?

Okay, so I've dabbled a little and successfully confused myself even more.
Let me boil things down.
As I mentioned, I am interested to know if there's a correlation between Anxiety (AN) and Hyperactivity (HA). Does HA go up when AN goes up? Aside from being a very small N, the data also are not normally distributed, so I've been working with nonparametric measures.
Based on the suggestions so far, I ran the means for each student for the two variables. I re-ran the Spearman, Kendall's, and Somer's and found that there was a very poor correlation between AN and HA.
I structured the data:
Mean_AN Mean_HA
St_1 10.33 10.00
St_2 28.67 14.83
St_3 26.17 16.67
St_4 25.10 26.30
St_5 20.50 22.30
St_6 41.50 25.70
St_7 31.75 30.50
If there were no data points missing (those pesky 0's in my data set), and if the N was more substantial, and if I had only kept up with my piano lessons as a kid and I were now conducting at the Met instead of a doctoral student in psychology, would you say that I've chosen the correct measures for my data set and structured it properly in SPSS? Would you say that there is a chance the outcomes of the procedures I've run are useful to me in accepting or rejecting the Null Hypothesis, which in this case is that I should go back to piano (My mother's null hypothesis that I would amount to Null if I gave up the piano)?
Seriously, thanks for your thoughtful feedback.
