5. Descriptive Research Purpose – To describe what is in reality Strengths –Certain descriptive research methods can be quick –You can generalize (apply to more than just those from which you sampled) your findings with some descriptive research methods Weaknesses –Can’t help you predict –Can’t give you cause and effect –Each descriptive research method has their own weaknesses as well

6. 3 Types of Descriptive Research 1.Naturalistic Observation 2.Survey 3.Case Studies

7. Correlational Research Purpose – to show relationship between two variables. Strength – If you know how they are related you can predict outcomes. Weakness – Correlation is not causation.

8. Experimental Research Purpose – to establish cause and effect relationships between variables. Strength – You find out if one variable (IV) causes a change in another variable (DV) Weakness – Confounding variables, experimenter bias, etc.
