Mr. Jones, a physical education teacher, notices that some of his students are better basketball players than others.
He wonders if having a basketball net at home fosters the development of basketball skills. He gives his students a short survey that asks them if they have a basketball net at home. Sure enough, Mr. Jones finds that the better basketball players are more likely to have a net at home. He concludes that having a basketball net at home facilitates the development of basketball skills. Is his conclusion appropriate?
a. No, because he didn't conduct an experimental study
b. No, because his study wasn't conducted in a scientific laboratory
c. Yes, provided that his students responded truthfully to the survey
d. Yes, because he used random assignment
