AP PSYCHOLOGY

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: -An experimental group is a test sample or the group that receives an experimental procedure. This group is exposed to changes in the independent variable being tested.

Detailed explanation-3: -Treatment groups are the sets of participants in a research study that are exposed to some manipulation or intentional change in the independent variable of interest. They are an integral part of experimental research design that helps to measure effects as well as establish causality.

Detailed explanation-4: -Scientific experiments often include two groups: the experimental group and the control group. Here’s a closer look at the experimental group and how to distinguish it from the experimental group.

Detailed explanation-5: -A test group is the name given to the entire group of users who will be analyzed as part of a study. So, if you’re running a mobile A/B test and the variables are being sent to a set proportion of users, your test group will be the total number of users being sent either variable.
