An experiment will be conducted in which 20 pepper plants are randomly assigned to two groups. The plants in Group 1 will receiv
e the current fertilizer, Fertilizer A, and the plants in Group 2 will receive a new fertilizer, Fertilizer B. All other growing conditions, including amount of sunlight and water, will be kept the same for the two groups. The growth of the pepper plants will be compared for the two groups. What are the experimental units in this experiment? A. The two types of fertilizer
B. The sunlight and amount of water
C. The 10 plants in Group 1
D. The 10 plants in Group 2
E. The 20 plants in the two groups
The experimental units in this experiment are the 10 plants in group 2.
The experimental unit is a term used in science to refer to an individual or group of objects that are initially equivalent and then undergo experimental processes.
According to the above, the experimental unit of this experiment is the group 2 of plants because these are the plants that are going to be put into experimentation with a new fertilizer.
Then, the answer is D, because it refers to the experimental unit corresponding to this experiment.
