Which statistical analysis should I use for the study

I am doing a research on 20 participants where 10 will be from computers background and rest will be from non computing background.

Each participants will attend a lab session and the performance of the participants will be evaluated based on a rubric. Each row of the rubric is evaluated on scale of 1 to 4.

The research question question is: does backgroundof the participant effect to play in learning about xxxx.

Which statistical method should I use to analyze the data?

Some more information would be helpful in coming to an answer. For eg. How do you define your outcome variable i.e "learning about xxxx". Is it a simple yes/no outcome or an outcome with several categories or an outcome with some kind of a continuous scale? –  Ariel Apr 9 '12 at 23:00
I am looking for just yes/no outcome. –  Dumb_Shock Apr 9 '12 at 23:03
Do you just have one variable of interest to assess - ie. computing background? –  Ariel Apr 9 '12 at 23:07
@ariel : Yes... –  Dumb_Shock Apr 9 '12 at 23:13
Well, in this case, I would say the easiest way would be to just compute an odds ratio with a 2X2 table. Your outcome would be Learning: YES/NO and your exposure variable is Background: Yes/No. Quick how to: intmedweb.wfubmc.edu/ebmreviews/odds.html –  Ariel Apr 9 '12 at 23:20
