Define and describe issues to be studied, form a hypothesis, choose an appropriate research strategy,conduct study, analyze data to support or reject hypothesis
Hypothesis
Predictive - specific prediction or set of predictions about the relationship among variables.
Casual - one variable will influence another variable
Population of interest
People researchers are interested in studying
Sample
Portion or sunset of the population of interest
Representative Sample
The sample should reflect the whole population as much as possible
Random sample
Every member of the population has an equal chance of being selected to participate in the study (avoids sampling bias)
Sample of convenience
Groups who are easily accessible to researchers
Naturalistic Observation
Research studies that are conducted in the environment in which the behavior typically occurred
Case Study
In depth observation of one participant
Surveys
Asking a large group of people about their attitudes, beliefs, and behaviors
Correlation Studies
Studies relationship between 2 or more variables
Correlation Coefficient

Negative Correlation
A relationship in which increases in one variable corresponds to decreases in the other variable
Independent variable
Variable that is manipulated
Dependent Variable
Variable in an experiment that measures any affect of the manipulation
Experimental Group
Group that receives the manipulation
Control Group
Group who do not receive the manipulation
Confounding Variables
Any factor other than the independent variable that affects the dependent measure
Quasi-experiment
A research study that is not a true experiment because participants are not randomly assigned to conditions
