who to control one variable at time
If you test only one variable then you know that the difference in the experimental and control setup is that one independent variable. If you test more than one you will not know which one made the difference.
The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
A control variable means an experiment that does not change, and it's used to validate results. For example, one want to test how two plants would grow, one needs to give each plant the same amount of water at the same time.
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
study one variable at a time.
it depends the one you wish to control in the experiment , for example if the temperature was measured every minutes so the controlled variable is time...
Control Variable is the answer

The Independent Variable is the one you change (Independent = I change)The Dependent Variable is the one you measure (It depends on something else)The Control is the one you keep the same! :)

The Independent variable is the one you control. The dependent variable is controlled by the Independent Variable.
a control variable is a variable that needs to be controlled
The variable that goes on the y axis is the dependent variable. This is the one that you measure, and do not control. The variable that goes on the x axis is the independent variable. This is the one that you control and change throughout the experiment. No other variables feature on the graph.
There are not any similarities between a control and a variable. However, a Control Variable, is a variable.
I will change the independent variable in my investigation. This variable is the one I manipulate or control to observe its effect on the dependent variable.
