A crime victimization study was undertaken in a medium-size southern city. The main purpose was to determine the effects of being a crime victim on confidence in law enforcement authority and in the legal system itself. A questionnaire was administered to a stratified random sample of 40 city residents; among the information elicited were data on the number of times victimized, a measure of social class status (SCLS), and a measure of the respondent's confidence in law enforcement and in rhe legal system. The data are reproduced in the following table.
