An experiment is designed to determine if wheat grows better when it is planted alone or with clover. The design calls for 3 pans of each treatment. Pans A, B, and C contain only wheat. Pans D, E, and F contain clover and wheat planted in alternating rows. Each pan contains a total of
100 seeds. All treatments contain the same type of soil, are planted in the same size pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment.
The treatments planted with only wheat are the
sample size.
control.
