perhaps you could organize like this
know who you're asking: ask different classes, grades, and equal amounts of boys and girls
what to ask: ask what mode of transportation each student takes to school each day, after that, ask about their grades
how to organize: one way to organize is by figuring out the grade avarage for each mode of transportation. putting this into a box and whisker plot may help to really show the differences in the grades
(hope this helped!)
