Answer #1

4. Correct Answer: D

The Independent variable is the variable which is manipulated by the researcher. The effect of manipulation of the independent variable is seen on the dependent variable.

5. Correct Answer: D

The dependent variable is the effect of the manipulation of the independent variable. The dependent variable is measured in a study.

6. Correct Answer: B

One-way experimental design means that there is only one independent variable in the study. Only the effect of one independent variable is measured.
