The variable being tested. The difference between the two groups after the experiment will ideally show some effect by the variable element.
control groups are those which you keep constant you don't do anything to them and experimental groups are the ones which you are adding something to it to see what happens
A factor that is kept the same between the control and experimental groups is called
it is the groups in experiment
In an experiment, having more control groups than experimental groups is not a strict requirement; rather, it depends on the specific research question and design. Control groups serve as a baseline to compare the effects of the experimental conditions, so having multiple control groups can help account for variability and confounding factors. However, too many control groups may complicate the analysis and interpretation of results. The key is to balance the number of control and experimental groups to effectively address the research hypothesis while maintaining clarity in the findings.
The control and experimental groups differ in that the experimental group is exposed to the treatment or intervention being studied, while the control group is not. This allows researchers to isolate the effects of the treatment and compare it to a baseline.
Independent variable
experimental and control
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.
The control is a group that is held constant and is not experimented with, The experimental group is the group that is experimented with
the number of participants in both groups are usually the same
experimental and control groups
You need a control group and an experimental group.
