Chapter 5:
Research Design
Key Attributes
External Validity
generalisability refers to whether the observed associations can be
generalised from the sample to the population
Constuct Validty
examines how well a given measurement scale is measuring the theoretical
construct that it is expected to measure
Statitical Conclusion Validity
examines the extent to which conclusions derived using a
statistical procedure are valid.
Internal Validity
Controls
manipulation,
elimination,
inclusion, and
statistical control,
and randomisation.
causality, examines whether the observed change in a dependent
variable is indeed caused by a corresponding change in a hypothesised independent variable,
Cone Validity -
higher degrees for internal and external validity
field experiments, longitudinal field surveys, and multiple case
studies
Interpretive methods
theory building
case research, phenomenology, and ethnography
Positivist methods
theory testing
laboratory experiments, field experiments,
field surveys, secondary data analysis, and case research
Popular Research Designs
Experimenta
l studies are those that are intended to test hypotheses
Field surveys
are non-experimental designs that do not control for or manipulate independent
variables or treatments
Secondary data analysis
is an analysis of data that has previously been collected and tabulated
by other sources
Case research
is an in-depth investigation of a problem in one or more real-life settings over an extended period of time.
multiple case design
Focus group
research
is a type of research that involves bringing in a small group of subjects
at one location
Action research
assumes that complex social phenomena are best understood by introducing
interventions or ‘actions’ into those phenomena and observing the effects of those actions
Ethnography is an interpretive research design inspired by anthropology that emphasizes
that research phenomenon must be studied within the context of its culture
cross-secctinal
longitudinal
quasi-experimental
true experimental
