Profiling, a procedure for evaluating methodological adequacy, a prerequisite for the acceptance or rejection of the conclusions of the investigation, is discussed. Three elements of this procedure are presented: (1) structuring of a logical argument, (2) generation of data and (3) analysis of data. All three elements are employed in hypothesis testing, and the second two are employed for empirical studies. Three aspects of data generation: representativeness, treatment and measurement are presented graphically as dimensions for the research quality cube. Ordinal scales, to facilitate profiling, are given for each of the three dimensions. Problems of data analysis are noted and the development of grids for the profiling analysis procedure is explained. Flow charts for guiding the research profiling are appended. (LR)
