Presentation on theme: "Explication and interpretation"— Presentation transcript:
1Explication and interpretation The essence of empiricism
2ExplicationExplication is a deductive process where you take a general concept, refine it, determine how to test for it and then carry out the testInterpretation reverses the processYour handout is an idealized model of explication and interpretationConstructMeasureDataConcept
3Your literature review guides your explication It helps assure that you include all of the major relevant theories and constructs in your study.It provides examples of methods, measurement instruments and their use.Prior studies should include their own explication of important concepts.Were they successfully applied in earlier studies?It helps you to anticipate common problems researchers studying your topic have facedWhat traps did researchers fall into in the past?
4ConceptualizationThe process of defining concepts concretely and narrowly enough to develop valid measuresDeveloping constructs to use in researchConceptConstruct
5OperationalizationYou must come up with ways to measure your concepts and/or test your theories in the physical worldChoose a research methodDevelop measures of your conceptsIncludes defining the theoretical relationship in measurement termsConstructMeasure
6Data collectionOnce you have designed your study you must carry out the research in the physical worldThings never go exactly as planned, so you have to make choicesYou must try to limit/eliminate real-world ‘noise’Chosen research methods,including measuresReal-world data collection

10Multiple concepts in a given study Up to now, we have only looked at a single concept, construct, method, data relationshipTo test a theory, you have to explicate at least two concepts and the relationship between themAs you saw with regard to the models shown in class, there are often quite a large number of concepts explicated in a given studyTo be practical, they all will most likely need to be measured in similar waysUsing different methods for different concepts leads to great difficulties and expanded costs, etc.
