Random vs. Non-Random Sampling in Class Research Projects

This paper examines the issues and practicality of probability and non-probability sampling in research methods class projects. Students conducted both probability (random sample of student residence hall rooms) and non-probability (availability) sampling on campus in a Fall 2006 class project. Discussion of the sampling issues involved in using both sampling methods in an in-class situation as well as comparison of the outcomes from both methods will be examined. A sample of 238 students on campus, is used to compare the two methods of sampling. Findings include analyses of demographic characteristics of subjects in both sampling methods as well as differences between samples for independent and dependent variables. Students' accounts of lessons learned is also included.
