Detailed explanation-1: -The treatment group (also called the experimental group) receives the treatment whose effect the researcher is interested in. The control group receives either no treatment, a standard treatment whose effect is already known, or a placebo (a fake treatment to control for placebo effect).
Detailed explanation-2: -A control group is an experimental condition that does not receive the actual treatment and may serve as a baseline. A control group may receive a placebo or they may receive no treatment at all.
Detailed explanation-3: -A placebo-controlled trial is a trial in which there are two (or more) groups. One group gets the active treatment, the other gets the placebo. Everything else is held the same between the two groups, so that any difference in their outcome can be attributed to the active treatment.
Detailed explanation-4: -The control group in an experiment typically receives placebo treatments (in this case-Group E). Since all of the other groups are receiving at least one dose of the medication, they are considered to be experimental groups.
Detailed explanation-5: -A control group consists of participants who do not receive any experimental treatment. The control participants serve as a comparison group.
