Research: measurements, operationalizing, ethics Flashcards
Material from chapter 3 and 4, and lecture 5 and 6
hypothesis
argues relationship between concepts
Parsimonious
As simple as possible
Inductive/exploratory research
Theory building, simple, generalizable, testable
Deductive approach
Theory testing, establish causal mechanisms
Typology
classifying by general type, similarities
Continuum
progression or sequence of values
Unidimensional concept
measures a single thing
Multidimensional concept
many aspects measured and involved
Value in research of:
Conceptual definition
Best to establish one that is widely accepted
Causality
statement that shows how variables are related
Correlation
statement that shows that variables are related
Determinism
idea that everything has a cause, should try to explain cause and effect
Hypothesis
Specifies expected relationship between variables
Falsifiable hypothesis
Possible to collect data to prove
Temporal order
Timing of events, challenging to collect in research
Confounding variable
Related to both variables, creates spurious relationship
Null hypothesis
Default, assumes no relationship between the variables
Bivariate relationship
One independent variable, one dependent variable
Causal models
Visual representation of a causal chain
Intervening variable
Between IV and DV (positive or negative)
Conditional variable
sometimes strengthens relationship between IV and DV within subgroups, but could weaken for others
