Answer to Question 1

Correct Answer: 2
Rationale 1: Quasi-experimental design is when the investigator manipulates the independent variable but without either randomization or control.
Rationale 2: Experimental design is one in which the investigator manipulates the independent variable by administering an experimental treatment to some participants while withholding it from others. This would be the situation if some of the participants were exposed to new products while others were not.
Rationale 3: In a nonexperimental design, the investigator does no manipulation of the independent variable.
Rationale 4: A pilot study is a test study before the actual one begins and is not a type of research design.

Answer to Question 2

Correct Answer: 2
Rationale: This option is an example of an independent variable, or something that can cause or have an influence on the dependent variable.
