Statistics were not my favorite class. But from what I think you say here and my understandings of Quartiles I don't see how the following rankings in my email:
Effective use: In the top 25% of all submitted applications Polish: In the top 25% of all submitted applications Indispensability: In the top 25% of all submitted applications Originality: In the top 25% of all submitted applications would explain the top 50 rankings. I can only guess that the raw scores were so *low* overall that the few people who scored big in a couple areas must have carried them to the finish line. If these were independent rankings then 1800/4=450 /4=112 /4=28 /4=7 would be the worst spot one might imagine with this email. So, I am guessing that the raw scores did play a significant role in final selection. On May 16, 9:05 pm, "David M.
