The researcher may have a hypothesis. The purpose of a correlational design is to examine relationships between or among two or more variables in a single group.

Answer to Question 2

Control means having the power to direct or manipulate factors to achieve a desired outcome. The researcher uses the controls of matching subjects and random selection.
Causality means that one thing leads to another.
Manipulation is not a form of control, but creates the control through the intervention or treatment. Control means having the power to direct or manipulate factors to achieve a desired outcome.
Nonprobability sampling does not hold random selection or assignment as criteria for participant sampling techniques.
