Hi everyone

I have a data set where the data is split into different groups.
Scores have been indexed on the average for the entire data set ie
scores for the average is all 100. Can anyone tell me a simple formula
for calculating whether the score for a particular group is
significantly above or below the score for the (indexed) average.

Thanks in advance!
