Textbook Question
Chapter 1, Problem 10TY
What is the purpose of using a control group in a scientific experiment?
- a. A control group allows the researcher to practice the experiment first before actually conducting it.
- b. A researcher can compare the results in the experimental group and control group to determine if a single variable is causing a particular outcome in the experimental group.
- c. A control group provides the framework for the entire experiment so the researcher can recall the procedures that should be conducted.
- d. A control group allows the researcher to conduct other experimental changes without disturbing the original experiment.
- e. all of the above.

- The 'control group' is an essential component of an experiment. This is because 1. A control group allows one to determine if a particular result is due to the experimental variable. 2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment. 3. A control group allows for multiple variables to be tested at the same time. 4.
