There is not enough information.
The percentile is the percentage of people who scored lower than a certain score.
All that can be said is that the percentile is no more than 50%, since the median 78% is higher than 74%.
Hello all,
I have a question about determining percentile on a test. I am given mean (77%), median (78%), and standard deviation (8). I scored a 74%, and there were 102 test takers. If possible, could you explain to me how to calculate my rank on the test or percentile?
Thanks so much!
