Question

experimental group

control group

variable group

independent group

​

Answer 1

Control group , it’s not being changed

Answer 2

Answer: control group

Step-by-step explanation:

The control group is the one which is used in an experimental set up as a benchmark for the comparison of the changes that occur in the experimental variable or dependent variable. It is the group which does not receive any experimental treatment. The use of a control group in an experiment increases the accuracy of the results of the experiment. It is the group which is treated normally without causing any change.
