Document Summary
Chapter 3 - quantitative research: theory, hypothesis, research design, devise measures of concepts, select research site(s, select research subjects/respondents, administer research instruments/collect data, process data, analyze data, findings/conclusions, write up findings/conclusions. Operationalization - a term derived from physics to refer to the operations performed to measure a concept such as temperature or velocity. Face validity - the measure apparently reflects the content of the concept in question. Concurrent validity - employs a criterion on which cases are known to differ and that is relevant to the concept in question. Predictive validity - researcher uses a future criterion measure, rather than a contemporary one. The researcher would take future levels of absenteeism as the criterion against which the validity of a new measure of job satisfaction would be examined. Construct validity - researcher is encouraged to deduce hypotheses from a theory that is relevant to the concept.
