research aims
|
broad statements (not questions) that include the entire intent of the work being done. Not necessarily well operationalized yet.
|
|
research questions
|
questions often split up into more general and more specific questions, often taking the form of a hierarchy of questions.
|
|
research hypotheses
|
statements about the relationships you expect to find between constructs. created based on your question.
|
|
directional ("one-way" or "one-tailed") hypothesis
|
when the direction of the expected relationship is predicted based on theory or prior work
|
|
nondirectional ("two-way" or "two-tailed") hypothesis
|
when the direction of the relationship is not predicted
|
|
deductive research
|
looks at theory and specifies a fact that the theory predicts, thus, there must be a hypothesis. theory>hypothesis>observation>confirmation
|
|
inductive research
|
looks at facts and creates theory, purely inductive research never has hypotheses. Observation>Pattern>Tentative Hypothesis>Theory
|
|
causality
|
must have 1) association 2) time order and 3) lack of spurious causality
|
|
spurious causality
|
when the relationships between two factors (A and B) is caused by a third factor (X)
|
|
internal validity
|
a study that measures the constructs and variables is says it's measuring (no threats to internal validity)
|
|
Sampling terms
|
Universal Population (Everyone)>Population of interest (who you want to generalize to)>Sampling frame (people eligible)>Study Sample
|
|
random assignment
|
randomly assigning your study samples (subjects) to a treatment and control group
|
|
Threats to Internal Validity
|
History
Maturation Testing Instrumentation Selection Mortality |
