The benefit of this descriptive research is that it allows researchers to view naturally occurring behaviors without controlling the situation.

• Natural observation

• Survey

• Case Study

• Correlation

The variable manipulated by the researcher is the

This is an example of

• Positive Skew

• Negative Skew

• Positive Correlation

• Negative Correlation

• Debriefing

In an experiment, the variable that changes in response to independent variable is known as
