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

No, because he didn't conduct an experimental study

Explanation:

When carrying out a study or research, it is appropriate to take out time and do a proper research, which not only involves assumption but also getting to see the results through observation. The judgement by Jones is inappropriate and would stand as being incorrect due to his conclusion was relatively an assption than a proper study, which assumptions can be deceiving.
