What is the Relationship between Points per Game Scored and the Height of the Players in the NBA?
Introduction:
The NBA is one of the United States’ favorite sports leagues, with each team averaging 100 million dollars of income each year before expenses.

Another limitation is that not all players play the same position. The goals of different positions vary from scoring, defending, passing and many others. There are point guards, shooting guards, small forwards, power forwards, and centers. Not to mention that strategies involving these positions have specific players take shots rather than everyone attempting to.
Adding on that, there might be a limitation to the amount of data that was collected. Only having collected 64 pieces it would have been better to collect all players from the NBA to better reflect the full span of players.
Lastly, one reason for a lower PPG is the coach’s decisions or being suspended. Benching a player (sitting them out) would cause them less game time for the season and thus reduce their average.
Conclusion
In spite of the aforementioned limitations, the project was done according to plan and it was found that the chi squared calculation value of 0.242226345, which is less than the chi squared critical value of 3.841, thus accepts the null hypothesis that points scored are independent values to their player 's height. By analyzing this categorical data it helps disprove that if you expect points to be higher with height you will be wrong. Furthermore, the investigation clearly shows that there is almost no correlation between points scored and height by looking at the r-correlation coefficient. The r-correlation coefficient comes out to be -0.048247472 which is
