In a control, the scientists know what to expect what will happen in an experiment... it is used for comparison.
A variable is pretty simple. All it is, is the thing in the experiment that changes. There is usually only one of them in an experiment, and there are two kinds... Im sure you are familiar with them.
-An independent variable is when the scientist controls what they are looking for
-A dependent variable scientists dont control directly, but they measure for results

What is the difference between an experimental variable and a control variable?
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
Define manipulated responding and controlled variables?
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
What is the difference between dependent and controlled variables?
The controlled variable is the one that you chose to change while the dependant is the variable that changes because it is effected by the controlled variable
What is a controlled variable in experimental psychology?
A controlled variable is the thing that is kept consistent in between trials of doing an experiment. e.g: time is kept the same or kept consistent...
What is the difference between dependent and independent variables?
The independent variable is the variable being manipulated in the experiment in order to show the effect on the dependent variable. It is also called the experimental variable.The dependent variable is the variable being observed in the experiment. Changes in the dependent variable as a result of changes in the independent variable are observed, which is the purpose of the experiment. Dependent variable is also called the response variable.
