Question

A scientist plants two rows of corn for experimentation. She puts fertilizer on row 1 but does not on row 2. Both rows receive the same amount of sun and water. She checks the growth of the corn over the course of five months. What is acting as the control group in this experiment?
A: The corn without the fertilizer.

B: The corn with the fertilizer.

C: The amount of water.

D: The height of the corn plants.

Answer 1

The scientist puts fertilizer on row 1 but not in row 2 and then subject both rows to the same conditions. The corn without the fertilizer is acting as the control group of the experiment.

The control group in an experiment represents a group that does not receive the independent variable treatment. The group forms the baseline for the comparison of dependent variable data.

In this case, the independent variable treatment is the application of fertilizer. Row 1 represents the treatment group while row 2 represents the control group.
