Question

Megan wants to see if mice that are fed food A or B grow at a faster rate. She measures the mass of the mice on day 1, then divides them into two groups based on the type of food they will be given. She feeds each group the same amount of food at the same time each day. Does Megan have a control group in this experiment?

Answer 1

No, there is no control group because each group is treated under test conditions.

Answer 2

Answer:

No

Explanation:

It is an example of experimental group. Experimental group is defined as the group in an experiment under which each variable is tested, however, one variable is tested at a time.

On the other hand, control group is defined as the group which does not receive treatment by the researchers.

The only difference between the both group is that, under experimental group independent variable is changed but under control group it is held constant.
