Here are three potential comparative questions using continuous variables from the 400 student database: 1. How does the average height of male students compare to the average height of female students? 2. How does the average weight of students who live within 5km of school compare to students who live further than 5km from school? 3. How does the average time spent doing homework each night compare between students in Year 9 and students in Year 11? My best question is: How does the average weight of students who live within 5km of school compare to students who live further than 5km from school?
