Abstract

This case describes the situation faced by the general manager of the A's at the end of the 1980 baseball season. The A's star pitcher, in negotiating his contract, claims that attendance was noticeably higher at games in which he was the starting pitcher. Game-by-game data for the 1980 season on home attendance and 10 variables affecting attendance are given. The case is suited for use near the end of a module on regression. It can be used to (1) review the t-test for a difference in means and relate the difference to regression with a dummy variable, (2) illustrate the importance of a model-building framework, even if used to evaluate someone else's models, (3) illustrate the use of dummy variables, and (4) point out the difference between conditional and marginal inference. A student spreadsheet is available.The supplement to the A case, QA-0313, contains the results of several regression analyses of the A's 1980 home-attendance data and may be used with the A case to facilitate analysis of the situation. (The B case is QA-0283.)

THE OAKLAND A's (A)

Steward Roddey, general manager of the Oakland A's baseball team, stared at the attendance figures he had put together for the recently completed 1980 season (Exhibit 1). It was October 1980, and Roddey was in the middle of a difficult contract negotiation with the agent for Mark Nobel, one of the star players for the A's. Nobel and his agent had argued that, in addition to contributing to the recent success of the A's team, Nobel had also been an attraction at the box office. They claimed that people came to the game specifically to see Nobel pitch and that Nobel should be compensated accordingly.

Roddey believed there could be some truth to Nobel's claims but wanted to look carefully at the previous year's figures nonetheless. He put together the information in Exhibit 1 as a first step, recording everything he thought could possibly influence attendance. The next meeting with Nobel's agent was two weeks away, so Roddey had plenty of time to analyze the data.
