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
biased sample
sample for which the observations of the study cannot be generalized to the population
representative sample
sample for which the observations in the study can be generalized to the population
probability sample
sample drawn by giving individuals equal chance to participate in the study
stratified sample
sample based on dividing population into subpopulations (strata)
internal validity (causal)
the validity of inferences about whether an observed association between x and Y reflects a causal relationship from x to Y ( association, precede, non-spuriousness)
exploratory research
discover new social phenomena and construct new theories, for this purpose you can use various data sources and inductive reasoning
Choosing qualitative or quantitative
matter of degree rather than simple dichotomy, can also be used supplementary, first consider aims study then choose method
case study research
research that is in-depth examination of extensive amount of information about very few units or cases (organization, criminal gang, school) used to generate thick description and for exploratory purposes (critique: low external validity; however depends on aim and can be standardized with more cases )
administrative research
research in which the researcher uses data on human populations that are provided by official institutions such as governments, schools or hospitals
