what is a control ,variable, independent variable, experimental variabale, dependent variable
you can look in the dictionary of your science book or an online dictionary.
Here is one description.
An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.
A dependent variable is the response or measure of results.
Extraneous variables — other than the independent variable — potentially can affect the dependent variable, so they must be controlled. If possible, you try to keep them constant between the experimental and control group.
The experimental group receives the independent variable.
The control group is similar to experimental, except it does not receive the independent variable. Extraneous variables are balanced between experimental and control groups.
A variable is anything that can vary or change.
I hope this helps. Thanks for asking.
