Question

nick is conducting a controlled experiment to test whether music helps daisies grow faster. below are the steps to nick’s experiment: 1. plant daisies in two separate flowerpots. 2. place flowerpot 1 in a green room with music. 3. place flowerpot 2 in a similar green room without music. 4. give the daisies the same amount of food and water each week. 5. measure the growth of the daisies. 6. draw conclusions based on the data collected. which group is the control group in nick’s experiment? a. flowerpot 2 b. the green room c. the music d. flowerpot 1

Explanation:

In a controlled experiment, the control group is the one not exposed to the independent variable (here, music). Flowerpot 2 is placed in a green room without music, while Flowerpot 1 has music. So Flowerpot 2 is the control group as it lacks the experimental treatment (music) to compare with the experimental group (Flowerpot 1).

Answer:

A. flowerpot 2
