Subject: Whose handwriting is the neatest - boys or girls?

This is my question for my 5th grade Science Fair project this year.  I 
have already tested 216 1st to 5th grade boys and girls in my school and 
have judged their handwriting.  I had them use their neatest handwriting to 
write the sentence "This is a sample of my neatest handwriting."  Two 
judges scored the samples (I coded the papers so they didn't know if it was 
from a boy or girl) on a scale from 1 to 5 with 1 being sloppy and 5 being 
excellent.  The results showed that one of the sexes has slightly better 
handwriting over-all than the other sex (my hypothesis was right).  I am 
curious how you would answer this question and if your answer supports my 
test results.  

Thank you.
