3Characteristics of a Good Hypothesis
- In harmony with existing knowledge
- General in scope
- Comprehensive yet parsimonious
- Yield a large number of consequences distinct
from those generated by alternative hypotheses - Relevant to the question at hand
- Testable

6Establishing Causality
- Covariation
- Changes in presumed cause must be related to
changes in the presumed effect - Temporal precedence
- Presumed cause must happen before presumed effect
- No plausible alternative explanations

9Tradeoffs in Research Design
- Internal validity
- External validity
Tip Look for discussion of limitations

14Evaluating Statistical Analysis
- The basics
- Reasonable sample size
- Correlations
- Regression and adjusted R2
- Significance tests
- Take comfort from peer-review process
15Trade-offs in Research Design
- No perfect study ever!
- Knowledge grows through triangulation
- Analytical research can provide theoretical
framework - Survey might identify important issues
- Quasi-experiment with archival data to determine
generalizability (external validity) - Experiment on same topic to more firmly establish
causality (internal validity)
