chapter 3 methods Flashcards
reasons sociological research (3)
descriptive, explanatory and exploratory
measurement quality (2) (concepts)
1) measurement validity 2) measurement reliability
measurement validity
the degree to which measures reflect the theoretical concept that they are intended to measure
measures
variable used in emperical research (indicator, emperical variable, proxy)
concepts
constructs, theoretical variables
operationalization
translation of concepts into measures
simple concept
easily measured with emperical variables (age,weight)
complex concept
consists of different dimensions (crime, inequality)
dimension
aspect of theory variables
conceptualization
differentiation of various dimensions on theoretical variables for complex concepts
measurement reliability
the degree to which the measurement instrument gives the same result when repeating the observation of the same phenomenon
standardization
process of making identical procedures, questions/answers categories and other aspects of the measurement instrument
external validity (population)
the validity of inferences about whether the results of the study are generalizable beyond a specific study
population
the entire set of cases about which the researcher wants to draw conclusions
sample
a small set of cases a researcher selects from the population
