Juan is writing a paper about children who play team sports, and he has several potential research questions. Which is his best option?

A strong research question invites investigation and explanation rather than a simple yes-or-no answer or a list of facts. “How does playing a team sport affect a child’s development?” gives Juan a topic he can explore using research about physical, social, and emotional development. The other choices are narrower factual questions or ask about participation without clearly defining what Juan will investigate.
