Program Evaluators Handbook: Sampling Model.
One of six summaries of workshop sessions (See TM 000 130), designed to strengthen the evaluation of costly programs and their effects, this handbook presents an analysis of both random and nonrandom sampling errors by application of the Bayesian model. This model attempts to formalize the process and procedures of inference from data through explicit consideration of the researcher's beliefs, insofar as they bear upon the study underway. Thus, if he feels that nonresponse error, for example, is likely to be large, this feeling is incorporated into the model. Major error sources for each parameter are sampled and values of all the variables are determined to show how these parameters define the sampling problem. Another method involves formulation of error ratios in terms of certain established values. An example of the application of the model to a survey using mailed questionnaires is given. (LR)
