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.
What is the group of participants chosen for an experiment called?
When conducting an experiment, there are two groups. One group is called the experimental group. This is the group that the treatment is being given too. The second group is called the control group. This group is not given the treatment and is used to compare the experimental group with. An example would be: A new medicine for heartburn was being tested. The experimental group would be given the medicine. The control group would be given a sugar pill. When the treatment was done, the results of both groups would be compared and a decision would be made as to the medications effectiveness.
What is a quasi experimental design?
A quasi-experimental design is a design that resembles and experimental design but does not have the key ingredient of random assignment. They involve selecting groups that are used to test a variable but with no random pre-selection process.
What is a sentence that uses control group?
Control groups are used in experiments for comparison purposes.
What is a control group in psychology?
A control group is usually used in experimental psychology to study the effect of an intervention or treatment. Research in psychology covers a number of topics. Sometimes, in order to verify whether an effect is significant, it is necessary to compare two groups or more. One of these groups will be a control group. A control group will often present the same characteristics as the other groups but will not be exposed to treatment or intervention, contrary to its counterpart(s). For example, group A can receive a newly developed therapy for depression, whereas the control group will not receive this therapy. Later on, both depressed groups will be compared to determine if the therapy had a significant effect, or, in other words, if it worked. Another example pertains to social therapy. A researcher could study the effect of setting short terms realistic goals on attaining long term goals. As such, a group of students would receive help on how to set short term goals, how to reach them, how to deal with obstacles, etc to attain long term goals. The control group, also made of students, would not receive such an intervention and would be told to set up long term goals and try to achieve them. At the end of the research period, both groups would be compared to see whether the intervention in helping setting short term goals and achieving them made a difference in term of goal achievement.
What is the difference between a control groups and experimental groups?
The control is a group that is held constant and is not experimented with, The experimental group is the group that is experimented with
In a controlled experiment what term is used to describe the many factors that might be different between the experimental and control groups?
variables
Which term describes a type of independent variable used to compare differences in dependent varables?
experimental control

What is used as a way to compare values for a dependent variables in many experiments?
experimental control
Why do you need a control group and a experimental group?
A control group is not provided any treatment, while the experimental group is the one to which a treatment is applied. The control and experimental groups are chosen to be as similar as possible, so that the observed effect (if any) can be attributed to the variable: what only the experimental group consumes, uses, or participates in.
What experimental situation used as the basis of comparison is the?
control group
What is the difference of control group and the experimental group?
Experimental group has been exposed to the independent variable whereas the control group has not, and is often used to compare the experimental group's results against.
What does control as an experiment means?
A control sample or control group is used to compare with the experimental group or sample. The control sample ideally, should be exactly the same as the experimental sample except that you don't give your experimental treatment to the control sample. Afterwards you compare the 2 samples to see if your experimental treatment had any kind of effect. The control is like a reference point.
