Question

To test how fertilizer affects tomato plants, a farmer divided a field of young

tomato plants into 10 plots of equal size. The farmer then put fertilizer on half
of the plots and no fertilizer on the other half of the plots. What is the control
group in this experiment?

Answer 1

The plots with no fertilizer

Step-by-step explanation:

In an experiment, the control group is used as a comparison for the experimental group (the group being actively changed and observed).

So, in this experiment, the control group is the plots with no fertilizer.

This acts as a good control group because it provides a normal standard to show the effect of fertilizer on the tomato plants.

So, the control group in this experiment are the plots with no fertilizer.
