predict the dependent variable
independent variable
of key interest, we want to understand or forecast

changes the relationship between an IV and a DV
moderator variable

hypothesis
Formed BEFORE data are gathered
hypothesis
null, no relationship
Ho
alternative, some form of relationship
Ha
a statistic that measures relationships
correlation coefficient
what is negatively related to turnover according to Robbins?
strength of relationship (correlation coefficient)
manipulate the IV, gather data on the DV, and control many other variables
lab studies
good support for causality , control many possible extraneous variables
strengths for lab studies
artificial and not generalize to the real world
weaknesses for lab studies
The independent variable and the dependent variable is measured, in real world organizations
field experiment
Still manipulate the independent variable, Some insight into cause and effect, Strong statistical analysis, and more generalization to the real world
advantages of field experiment
Lose some of the insight into cause and effect and Hard to get cooperation from organizations
disadvantages of field experiment
Data is gathered on independent variable and dependent variable
field study
good measurement and rigorous statistical analysis
advantage of field study
Harder to make causal arguments
disadvantage of field study
Synthesis of many previous studies on a topic
meta-analysis study (phil’s FAVORITE study)
Rigorously combines all the studies together (consensus)
advantage of meta-analysis study
Results are little better than the studies that go into the analysis
disadvantage of meta-analysis study
the process of allocating personal resources (time, energy) to various behaviors to result in maximum satisfaction
