A controlled variable is one which is not allowed to change unpredictably during an experiment. Because they are ideally expected to remain the same, they are also called constant variables.
An example of a constant variable could be the voltage from a power supply. If you are examining how electricity affects an experimental subject, you would keep the voltage constant, as otherwise the energy supplied would change as the voltage did.

What is the definition of a variable?
operational definition of a manipulated variable
What is the scientific definition of a control variable?
A controlled variables are what stayed the same and is compared to other variables
What is the definition of a manipulated variable?
operational definition of a manipulated variable
What is control variable and manipulated variable?
a control variable is a variable that needs to be controlled
What are the similarities between a control and a variable?
There are not any similarities between a control and a variable. However, a Control Variable, is a variable.
What is the definition operational definition in science?
describes how to measure a variable or define a term. right out of my science book
Definition of manipulative variable?
Manipulated variable is also known as Independent variable and is the factor that you change in an experiment. For example if you were measuring the effects of alcohol on driving ability the manipulated variable would be alcohol, either with or without alcohol.
What do controlled variable do?
You can control it that's why its called control variable.
What is a control variable in research studies?
A control variable is a variable that is held constant in a research analysis.
How do you control one variable at time?
who to control one variable at time
Is a variable that stays the same a constant independent variable or control?
Control
Can the independent variable and the control variable be the same?
No, the independent variable and the control variable cannot be the same. The independent variable is what is being changed or manipulated in an experiment to observe its effect on the dependent variable, while the control variable is kept constant to minimize its impact on the results. Having them be the same would defeat the purpose of having a control variable.
