what is the difference between a variable and a control
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.
a control stays the same(under control) but the variable almost always changes
If an experiment compares an experimental treatment with a control treatment, then the independent variable (type of treatment) has two levels: experimental and control. If an experiment were comparing five types of diets, then the independent variable (type of diet) would have 5 levels. In general, the number of levels of an independent variable is the number of experimental conditions.
I still don't know?
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 the standard to which an outcome of an experiment is compared, but a variable is something in an experiment that can change.
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
Control Variable = kept in constant in a experiment Experimental Variable = changes in a 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.
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.
