Gold, Robert S. | Basch, Charles E. | McDermott, Robert J.
The utility of multi-matrix sampling as a technique in health education research is examined. This technique permits quality collection of large quantities of data without lengthy questionnaires or excessive time demands on respondents. Sampling approaches are explained. Potential applications can be seen for a variety of settings and purposes. Six advantages and 4 disadvantages are listed. Although data analysis for this method requires a computer, reduced cost and improved efficiency compensate for this data collection alternative as research funds diminish. (kbc)
