Question

Do highly performing athletic teams have a larger fan base and generate greater attendance at games or matches? Use the data (in the data document) for the number of wins and attendance in 2006 for the 14 American League baseball teams to answer the follow questions:

a) Examine a scatterplot for the 2 variables and test the conditions for regression.

b) Do you think there is a linear association between Home Attendance and Wins?

Team	Wins	Runs	Home Attendance
Minnesota Twins	96	801	28210
New York Yankees	97	930	51858
Toronto Blue Jays	87	809	28422
Cleveland Indians	78	870	24667
Chicago White Sox	90	868	36511
Texas Rangers	80	835	29490
Baltimore Orioles	70	768	26583
Los Angeles Angels	89	766	42059
Detroit Tigers	95	822	32048
Seattle Mariners	78	756	30626
Kansas City Royals	62	757	17158
Boston Red Sox	86	820	36182
Oakland Athletics	93	771	24402
Tampa Bay Devil Rays	61	689	16901

Answer 1

a) Scatter plot:

Given data was entered in Excel sheet and the following scatterplot was created

From the above plot it is noticed that there is a relationship exist between no of wins and home attendance. Therefore, we can use the regression to assess the relationship.

b) Possibility of Linear Regression:

From the scatterplot it is noticed that there is a straight line relationship, however after a certain point the point take a curve. Therefore, it can be infered that there is a curvi-linear relationship exist between the no of wins and home attendance. So, it can be said the relationship is more of curvi-linear relationship than the straight line relationship.
