Chapter 2 Flashcards
research methods
approaches that social scientists use for investigating the answers to questions
quantitative methods
methods that seek to obtain information about the social world that is already in or can be converted to numeric form
qualitative methods
methods that attempt to collect information about the social world that cannot be readily converted to numeric form
deductive approach
a research approach that starts with a theory, forms a hypothesis, makes empirical observations, and then analyzes the data to confirm, reject, or modify the original theory
inductive approach
a research approach that starts with empirical observations and then works to form a theory
correlation (or association)
simultaneous variation in two variables
causality
the notion that a change in one factor results in a corresponding change in another
reverse causality
a situation in which the researcher believes that A results in a change in B, but B, in fact, is causing A
dependent variable
the outcome that the researcher is trying to explain
independent variable
a measured factor that the researcher believes has a causal impact on the dependent variable
hypothesis
a proposed relationship between two variables
operationalization
the process of assigning a precise method for measuring a term being examined for use in a particular study
validity
the extent to which an instrument measures what it is intended to measure
reliability
the likelihood of obtaining consistent results using the same measure
generalizability
the extent to which we can claim our findings inform us about a group larger than the one we studied
