the Literature and Assumptions
The authors reviewed almost 40 studies in an effort to show the need for their study and the relation of the research to existing work in the field. The information was clearly presented and the study well justified.
The key assumption of the study concerns its dependent measures. It was noted that while the focus of the study was evaluating programs designed to reduce turnover, no actual measures of turnover were collected due to time and sampling constraints on the researchers. Rather, variables which prior research had shown to be systematically related (correlated) to turnover were measured.
This assumption that variables correlated with turnover can be used as indices of actual turnover
