3 Categories of Research
Experimental, Correlational, Descriptive
Experimental Research Method
Explore cause and effects
Independent Variable
the thing that we change/manipulate
Dependent Variable
the thing we measure (not manipulated)
Confounding Variable
the thing outside the experiment that influences the experiment (negative)
Population
The people that we are studying
Sample Of Population
If the population is too large a sample can be taken but it must be a proper representation of that group
Subject Groups
Control Group and Experimental Group
Experimental Group
Get the IV
Control Group
Do not get the IV (get a placebo)
Control Measures
Protect us from CV
Randomization
Picking different groups randomly

Participants don’t know which group they are in
Double Blind
No one knows what group anyone is in
Operational Definition
Empirical (can be physically tracked) measure of a vague team
Correlation Research Method
To detect naturally occurring relationships, comparing different pieces of data, correlation does not imply causation.
Descriptive Research Method
To observe and record behavior
Types of DR
Naturalistic Observations, Case Studies, Surveys
Naturalistic Observation
people watching (Don’t let them catch you)
