Question

testing hypotheses often involves designing experiments. which of the following is the factor that is observed or measured in an experiment?
a. control group
b. experimental group
c. dependent variable
d. independent variable

Explanation:

In an experiment, the dependent variable is what is observed or measured. The independent variable is manipulated, the experimental group gets the treatment, and the control group doesn't. So the factor observed/measured is the dependent variable (option C).

Answer:

C. dependent variable
