From observation we can make generalizations about human nature
and behavior.

Methods of Observation•Surveys
–Target population–Samples
•Random samples•Stratified samples
–Accuracy??•Generalizing Results•Volunteer Bias

• Testing– Types
• Case-Study– In-depth (individuals or groups)– Generalization, Replication, Recollection
• Longitudinal– Change/develop over time (expense, risk?)– Cross-sectional (reliability?)
• Naturalistic Observation– Field Study
• Laboratory– Control the environment

Correlation
• Correlation is the measure of how one thing is related to another.– Positive Correlation – one goes up, so does
the other– Negative Correlation – one goes up, the other
goes down• CORRELATION does not necessarily
mean CAUSATION.

The Experimental Method• Experiments – Used by researchers to answer
questions about cause and effect.
– Variables - • Independent Variable• Dependent Variable
– Groups• Experimental Group• Control Group
– Placebo Effect– Studies
• Single-Blind• Double-Blind
