The control group in this experiment is Tank A as it is fed the typical amount of food once a day, serving as a baseline for comparison with the other tanks receiving more frequent feedings.
Option A is correct
Independent variable (IV) is the number of times the goldfish are fed per day (once, twice, or four times).
Dependent variable (DV) is the weight of the goldfish.
Control Group is the group that receives the standard or normal treatment so that we can compare it to the groups receiving the experimental treatments.
Tank A: Fed once a day (normal amount, control group).
Tank B: Fed twice a day (experimental treatment).
Tank C: Fed four times a day (experimental treatment).
If we go ahead to compare the weight gain (DV) of Tank A (control) with Tanks B and C (experimental), we can assess the impact of the different feeding frequencies on goldfish growth.
complete question:
One tank of gold fish is fed the normal amount of food once a day. A second tank is fed twice a day. A third tank is fed four times a day during a six week study. The fish's weight is recorded daily. All tanks were of the same size and shape. IV: DV: Control Group: Which of the following is the control group in the above experiment
A) tank A
B) tank B
C) tank C
D) there is no control group in this experiment
