RESEARCH METHODOLOGY

Detailed explanation-1: -The negative control group is a group that does not receive changes to the independent variable. It is used as a benchmark to compare the results of the experimental group to.

Detailed explanation-2: -A control group in an experiment does not receive the treatment. Instead, it serves as a comparison group for the treatments. Researchers compare the results of a treatment group to the control group to determine the effect size, also known as the treatment effect.

Detailed explanation-3: -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: -A control group is used as a comparison for the experimental group. The control group is the group in an experiment that does not receive any change in the variable. This group is left as natural as possible and used as a control to see if there is a change from the normal results.

Detailed explanation-5: -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.
