Mall Intercepts and Clinical Trials:

The Philosophy of Inference from Different Types of Research Designs, Marketing Research: A Magazine of Management & Applications, Vol. 1, No. 1, March 1989.

Project details

 The author examines two methods of data collection and the problems of projecting results to a population.  Design issues endemic to any data collection technique can seriously affect a researcher’s ability to draw inferences from respondents actually studied to a population.  Mall intercept studies and clinical trials, two seemingly different techniques used for the study of important demographic traits, are shown to be similar in their ability to describe a population.
