Detailed explanation-1: -The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is “controlled” or held constant in the control group.

Detailed explanation-2: -A controlled experiment is defined as an experiment in which all the variable factors in an experimental group and a comparison control group are kept the same except for one variable factor in the experimental group that is changed or altered.

Detailed explanation-3: -What is the difference between a control group and an experimental group? An experimental group, also known as a treatment group, receives the treatment whose effect researchers wish to study, whereas a control group does not.

Detailed explanation-4: -The group that receives the treatment in an experiment (here, the watered pot) is called the experimental group, while the group that does not receive the treatment (here, the dry pot) is called the control group. The control group provides a baseline that lets us see if the treatment has an effect.

Detailed explanation-5: -In a controlled experiment, all extraneous variables are held constant so that they can’t influence the results. Controlled experiments require: A control group that receives a standard treatment, a fake treatment, or no treatment.
