I think this is wat ur tryin to get at ,
68% of The distribution lies within one standard deviation of the mean .
95% of the dist lies within two standard deviations of mean
99.7% of the dist. Lies within three sd of the mean .

Those would be the three Quartiles of a normal dist ... If u are trying to find out wat percentile a certain mean or # is out of a score there is a formula I can show u , u just didn't include enough info to even do a problem or Maybe I'm confused w ur wordin .. I got bars w stats tho if u ever. Need help !
