HISET Science Exam Questions and
Answers
Control Group - Answer-in an experiment, the group that is not exposed to the treatment
Dependent Variable - Answer-a variable (often denoted by y ) whose value depends on that of another.
Experiment - Answer-a test under controlled conditions that is made to demonstrate or test a
