Observation in a natural setting without interruption or control
Case Study
In depth, one subject or few, no generalization

Research Methods
Descriptive, Correlational, Experimental
Descriptive research
Describe what is occurring. Observational studies, Self-report, Case studies
Correlational research
Test relationship between variables
Experimental research
Investigate what causes an outcome
Observational studies
Watch participant in natural environment
Self-Reports
Surveys or interviews for information
Third variable effect
A third variable may influence variable one and/or variable two
Conducting an experiment
Random assignment, Experimental control, IV, DV
Experimental control
Control of variables that could influence outside effects. Eliminate excess influence
Control Group
Not exposed to IV
Experimental Group
Exposed to IV
Behavior
Observable Acts
