Variables in our data set that reflect a team's ability to score runs are home runs and batting average; a higher number of home runs and a higher batting average is assumed to be positively correlated to scoring more runs and thus earning more wins as a team. . Furthermore, if a team can prevent the opponent from scoring runs, then it is more likely to win the game. Earned run average (ERA) reflects the number of earned runs given up by a team's pitchers over the course of a 9-inning game. The lower the ERA, the lower the runs the team's pitchers give up during the course of a game, and thus a higher chance for the team to win (assumed to reflect a negative correlation or inverse relationship between ERA and wins). . Finally, a team with more talented players will presumably have a higher payroll due to the larger contracts the more talented players will demand and earn. Thus, it is assumed that a team's payroll is positively correlated to wins. We will analyze these assumed relationships and determine how much of a factor these variables play in predicting a team's number of wins in a given season. E. Determine the correlation coefficient for the following variables in relation to wins as well as the actual relationship between the independent variable listed and wins. Round your answers to 2 decimal places. . Use a zero in front of the decimal. . Use a negative in front of the zero if the correlation coefficient is negative. . Enter the actual relationship as Positive, Negative, or None. Correlation Coefficients with Wins Expected Actual Relationship Relationship ? HR Positive BA Positive ERA Negative Team Positive Salary F. Does the correlation coefficient analysis reflect any differences between the expected and actual relationships? Enter Yes or No
