Answer: zoe's question's data would vary because not everyone in her class could play video games for the exact same amount of time.
however this is not a statistical question because we do not know when the students are playing video game for example we wouldnt know if she wanted to know how much time a classmates spends playing video games each year, each month, each week, etc. so to make this a statistical question zoe would have to ask.... which student spends the most time a day on video games.
