Allegory of the Cave
What can Ms. Borsch conclude from these results? SQ. Ms. Patricia Wald, city manager Of Big Cat, Texas, believes that she has discovered an effective strategy to combat the problem of loitering. Ms. Wald believes that loitering will decrease dramatically when classical music is piped through the city outdoor speaker system, which has been installed on a few main streets downtown. The program is phased in gradually. Music is played on the system on some days but is purposely not played on other days.
This procedure enables the manager to compare differences in the number of individuals cited for loitering on music days and nonionic days. Ms. Wald runs a regression in which the number of individuals receiving either warnings or citations for loitering (LOOT) is the dependent variable. The independent variable is a dummy variable coded 1 for days when classical music is played on the outdoor speaker system, and O for days when music is not played (MUSIC).
What can Ms. Wald conclude about the effectiveness of this program from the regression results? SQ. Organizational theorist Ken Brier has obtained data on the composition of nonprofit boards of directors in the metro Chicago area. Professor Brier hypothesizes that the higher the percentage of major donors present on a road, the lower an organization’s fund-raising expenses should be. Data are available for a sample of 77 nonprofits.
