what is the difference between a variable and a control
A control group is a group that does not receive the experimental treatment and is used as a baseline for comparison, while a variable group is a group that is exposed to the experimental treatment. The control group helps researchers determine the effect of the treatment by providing a reference point.
There is one major difference of a treatment group and a control group. The treatment group is treated with an experimental medication (or known medication), and the control group is treated with a placebo in place of the medication to measure effects of the medication.
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 effect on the dependent variable will be different in the experimental group than the control group, which is why you measure the dependant variable.
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.
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
The difference between these both is that the control is what stays the same in an experiment and the variable is what changes.
control is when nothing is done to the experiment and controlled variable is that you have control over the experiment.
a control is a object that cant be changed in an experiment and a variable is a object that can be changed in a expirament
A control is the standard to which an outcome of an experiment is compared, but a variable is something in an experiment that can change.
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
The control variable is the thing you keep the same and is everything that is not the independent variable. The Control Setup is there for the sake of comparison.
There are not any similarities between a control and a variable. However, a Control Variable, is a variable.
A control group is a group that does not receive the experimental treatment and is used as a baseline for comparison, while a variable group is a group that is exposed to the experimental treatment. The control group helps researchers determine the effect of the treatment by providing a reference point.
The null hypothesis is the default hypothesis. It is the hypothesis that there is no difference between the control group and the treatment group. The research hypothesis proposes that there is a significant difference between the control group and the treatment group.
