research trinity
- design
(gathering info establishes validity) - measurement
collect info to determine constructs and insure reliability) - analysis
(establish conclusion validity and evaluates hypothesis)
descriptive stats
generate numbers to describe results
inferential stats
inferring to a population
sources of knowledge
- tradition
- authority
- trial and error
-deductive/inductive reasoning
deductive vs inductive
d - general observation to specific conclusion
I - specific observations to general conclusion

correlational-predictive research
examining relationship between variables (not cause and effect)
simple correlation
