POLI 110 Study Guide - Final Guide: Sampling Bias, Dependent And Independent Variables, Statistical Significance
Document Summary
An assumption is not something we are claiming is true. Rather, we"re saying that the causal logic only walks if or when the assumption holds. A measurable property of a phenomenon that can potentially take on different values. A variable takes on a value for a given case at a given point in time. An abstraction used to describe characteristics of a phenomenon, group, or individual. (concepts and variables are general, not specific) Dimensions are: apart of a concept, , could exist, disappear, change independently of one another (not redundant). Concept dimensions variable measure variable. The degree of fit between a measurement procedure for a variable and the concept that the variable intended to capture. How consistently a measure produces the same result. The measure does not cover enough of the concept. The measure covers things outside of the concept. The measure captures different things in different units. Variability in top-of-mind considerations (for survey/interview measures)
