Chapter 6 - Selection of research participants: Sampling procedures. This chapter includes contents: Subject selection and sampling, technical sampling terms, random processes in research, simple random sampling, systematic sampling,. | Chapter 6 Selection of Research Participants: Sampling Procedures Subject Selection and Sampling This is considered highly important in social and behavioral research Three basic questions to consider: 1. Are the research participants appropriate for the research question? 2. Are the research participants representative of the population of interest? 3. How many research participants should be used? Technical Sampling Terms Population – refers to an entire group or aggregate of people or elements having one or more common characteristics Sample – a small subgroup of a population of interest thought to be representative of that population Sampling – the process of selecting a subgroup or sample of the population Sampling Frame – the accessible population or collection of elements from which the sample is actually drawn Random Processes in Research Random Selection The purpose is to enable the researcher to generalize the results to a larger population. Thus, the researcher is concerned about the “representativeness” of the subjects in the sample Random Assignment The purpose is to enable the researcher to assume that groups are “equivalent” at the beginning of the study. This adds control to a study; it has nothing to do with the selection of the sample Sample Selection Methods Probability Sampling Sampling techniques in which the probability of selecting each participant is known Utilizes random processes, but does not guarantee the sample is representative of population Estimates of sampling error are possible Non Probability Sampling Samples are not selected at random Difficult to claim sample is representative of population Intact groups, volunteers Sample Selection Methods Probability Sampling Simple random sampling Stratified random sampling Systematic sampling Cluster sampling Non Probability Sampling Purposive sampling Convenience sampling Simple Random Sampling With simple random sampling, every member of the population has an equal probability of being .
