government, lasting for roughly 50 years (ending in the 1970s), in which a sample of African American men diagnosed with syphilis were deliberately left untreated without their knowledge, to learn about the lifetime course of the disease CHAPTER 4: Conceptualization and Measurement 1. What is a concept? (p.74) A construct? (p.74-76) (book and lecture)Concept – an image or idea that summarizes a set of similar observations, feelings, orideas Construct – the definition of your term as used in your research/study2. What is conceptualization? (p.75-76) A conceptual definition? What is operationalization?(p.78-79) An operational definition? How do rules of correspondence link these two processes? What does violating a rule of correspondence mean? (book and lecture)
Conceptualization – the process of specifying what we mean (ex: What does it mean to be black? And we decide in our study that it means you are 50% black)oThe link between concept and constructoConcept, you conceptualize it for your survey/study, construct is the resulting definitionConcept > operational definition > write survey and indicators (actual questions)How to know what to include in operational definitionoLiterature review, evaluate other definitionsoTheoryoMeasurement options3.What is a variable? (p.26-27) What is a constant? (p.76-77) List and briefly describe the four steps you should take when selecting variables. (p.77) (book and lecture)Four steps:1.Examine theories that are relevant to our research question to identify those concepts that would be expected to have some bearing on the phenomenon we are investigating2.Review the relevant research literature and assess the utility of variables usedin prior research3.Consider the constraints and opportunities for measurement that are associated with the specific setting(s) we will study. Distinguish constants from variables in this setting4.Look ahead to the analysis of the data. What role will each variable play in ouranalysis?4. What does it mean when response values are mutually exclusive? (p.82) Exhaustive? (p.82) (book)
