Bruce believes that male students in his physics course spend more time working on homework than female students. His teacher and classmates are skeptical, so they asked him for proof. Which of the following would be the best way for Bruce to prove his point?

To test Bruce’s claim, he needs to collect actual homework-time data from male and female students over multiple days, then compare the groups. Recording hours daily, totaling them, and displaying the comparison in a bar graph makes the evidence clear. A survey asking only whether students did homework does not measure time, and estimating an entire semester’s hours is likely to be inaccurate.
