Control groups are non-experimental groups -- that is, they have not been subjected to the experimental treatment. For example, if you are testing a new drug, the experimental group (also called the "treatment group") gets the drug, and the control group does not.
Control groups are necessary in order to show that the treatment causes an effect. If the experimental group shows changes, but the control group does not, then it is possible that those changes were caused by the treatment. If there is no control group, then there is nothing to compare the experimental group to.
Additionally, a control group is usually given an equivalent treatment. In the drug study, the control group would receive a placebo, such as a sugar pill. In such cases, control groups may be called placebo groups. This is done in order to show that any observed effects are caused by the treatment itself, and not by the process of administering treatment. In this way, we are controlling for the placebo effect -- a psychologically-induced response to a fake treatment, in which people begin to get well because they think they should be getting well.

Control groups are used in experiments to isolate the effect of the independent variable being tested. By comparing the results of the control group (not exposed to the independent variable) with the experimental group (exposed to the independent variable), researchers can determine the true impact of the variable being studied. Essentially, control groups provide a baseline for comparison in scientific studies.

Are control groups and experimental groups the same thing?
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.
How would someone equalize the intelligence of members of the experimental and the control group in a experiment?
One way to equalize the intelligence of members in the experimental and control groups is to use random assignment of participants to the groups. This can help ensure that any variability in intelligence is distributed evenly across the groups. Additionally, researchers can use matching techniques to pair participants in the two groups based on intelligence levels.
Do you have a control group when you use qualitative writing?
Control groups are more commonly used in quantitative research to compare outcomes with a standard or no treatment group. In qualitative research, control groups are not typically utilized since the focus is on exploring experiences, perspectives, and meanings rather than testing hypotheses with controlled variables. The emphasis is on in-depth understanding rather than statistical generalizability.
The procedure designed to ensure that the experimental and control groups do not differ in any way that might affect thee experiment's results is called?
The procedure is called random assignment. It involves randomly assigning participants to either the experimental group or the control group to help ensure that any differences in the groups are due to the treatment being tested and not other factors.
What is the difference between a control variable and a control treatment?
A control variable is a factor that is held constant in an experiment to prevent it from influencing the outcome. A control treatment, on the other hand, is a specific group or condition in an experiment that receives no experimental manipulation and is used as a baseline for comparison with the treatment groups.
