Essay On Shoring Points

Vince Lombardi once asked “If it doesn 't matter who wins or loses, then why do they keep score?” Scoring points is a major factor in winning a football game, but stopping the opposing team from scoring helps too. So you might simply ask, just how important is scoring points versus the amount of points that a team allows to be scored on them? Here the correlation between three variables will be examined to come to a consensus of whether the points scored or points allowed correlates with the total number of wins. Like any observational study, it is important to come up with a basic hypothesis regarding the data that one is presented with, before any action of analysis. In this case, due to the two separate sets of variables that are being observed, there are two hypotheses. The first being that the …show more content…
As for the relationship between points allowed (x) and total wins (y), there is a negative correlation. This is so because the teams that generally allow more points to be scored on them by their opposing team would tend to lose the match, resulting in the assumption that the more points that are allowed by a team would result in a decrease of wins that a team would receive. To gather data for points scored (x) and total wins (y), and points allowed (x) and total wins (y), the systematic sampling method was used. Every other team (outlined in red, shaded in gray) was selected from the NFL data sheet. As the first scatter plot (Points Scored vs. Total Wins) proves, as the points scored increases, so does the total number of wins. On the other hand, the second scatter plot (Points Allowed vs. Total Wins) proves, as the points allowed increases, the total number of wins decreases. The calculation of the correlation coefficient (r) between points scored (x) and total wins (y) is 0.754 meaning that there is a strong uphill (positive) linear relationship between the two
