Help deciding what stats to run in SAS to determine effect of Obs bias on Group Size

#1
Hello,

I'm trying to determine if the observer group size of a study ( 1, 2, 3) and experience of the observer impacts the potential for observer bias ( Type 1 and 2 errors) when conducting auditory surveys. I'm going to analyze my data is SAS 9.3 and was hoping people would have some advice as to what tests to run. Any help would be appreciated as i'm new to SAS ( and frankly rusty on BioStats)

Thank you in advance for any advice you may have.
