Hello!

3. How does temperature affect a football players performance?

Independent Variable: Temperature

Temperature is the independent variable because that is what you are testing.

Dependent Variable: Points scored in game

Since you are attempting to measure how well football players do in different climates, you must measure their scores.

Constants: Uniform, field played in, and ball used

If you use a different uniform, field, or ball, then the data is obviously going to be inconsistent.

Hypothesis: If football players are in colder climates, then they perform better during games.

This is quite self-explanatory: just use the latter data points to craft your hypothesis. Keep in mind that a hypothesis should NEVER be a question!

I hope I helped! :-)
