1.66 Does rudeness really matter in the workplace? Studies have established that rudeness in the work- place can lead to retaliatory and counterproductive behavior. However, there has been little research on how rude behaviors in?uence a victim's task performance. Such a study was conducted and the results published in the Academy of Management Journal (October 2007). College students enrolled in a management course were randomly assigned to one of two experimental conditions: rudeness condition (45 students) and control group (53 stu- dents). Each student was asked to write down as many uses for a brick as possible in 5 minutes. For those students in the rudeness condition, the facili- tator displayed rudeness by berating the students in general for being irresponsible and unprofessional (due to a late-arriving confederate). No comments were made about the late-arriving confederate for students in the control group. The number of dif- ferent uses for a brick was recorded for each of the 98 students and the data saved in the RUDE ?le, shown below. Conduct a statistical analysis
(at α = .01) to determine if the true mean perfor- mance level for students in the rudeness condition
is lower than the true mean performance level for students in the control group.
