What is another possible explanation for the correlational relationship between scoring more points per game and making more money? Since this is just a correlation, we can't be sure if scoring more points per game causes players to make more money. So, What is one possible other explanation that you can come up with for the correlation that you calculated (hint: think about possible 'third variable' explanations for this correlation–what other variables or factors might be causing changes in both points per game and salary that could explain this correlation)?
