Describe the Function of a Control Group in an Experiment
In an experiment the control group is the group that remains independent of the experiment for the purposes of comparison. They should be identical in all other ways.
The control group is similar to experimental except it does not receive the independent variable.
. Single blind gives the control group a placebo a substance that is inert it has no physical effect. In experiments scientists compare a control group and an experimental group that are identical in all respects except for one difference - experimental manipulation. This isolates the independent variables effects on the experiment and can help rule out alternative explanations of the experimental results.
Researchers compare the results of a treatment group to the control group to determine the effect size also known as the treatment effect. Extraneous variables are balanced between experimental and control groups. When conducting an experiment these people are randomly assigned to be in this group.
What is the function of a control group in an experiment. AIt is the group that always changes. An experimental group also known as a treatment group receives the treatment whose effect researchers wish to study whereas a control group does not.
If the experiment is testing a. Unlike the experimental group the control group is not exposed to the independent variable under investigation and so provides a base line against which any changes in the. Instead it serves as a comparison group for the treatments.
They also closely resemble the participants who are in the experimental group or the individuals who receive the treatment. The function of a control group is to act as a point of comparison by attempting to ensure that the variable under examination the impact of the medicine is the thing responsible for creating the results of an experiment. A control group is a group separated from the rest of the experiment such that the independent variable being tested cannot influence the results.

The control group is composed of participants who do not receive the experimental treatment. Describe the function of a control group in an experiment. The most powerful experiments have two types of control groups a positive and negative control group.
