Variables are properties or characteristics of some event,
object, or person that can take on different values or amounts.
When conducting research, experimenters often manipulate variables.
For example, an experimenter might compare the economies of three different countries:
Tunisia-
in this case each country is a variable.
hence a variable serves to show variation i.e changes of a statistic or parameter.
The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment.
The dependent variable is the variable that can change in an experiment.
What is a variable in a experiment
variable is a factor in an experiment that can change
it is easier to manipulate when you have several controls and only one variable
The factor in an experiment that is changed on purpose is called the independent variable. This variable is manipulated by the researcher to observe its effect on the dependent variable. It is the cause being studied in the experiment.
A manipulated variable, also known as an independent variable, is the variable that is intentionally changed or controlled by the experimenter in an experiment. Its purpose is to determine the effect it has on the dependent variable.
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.
The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment.
The variable that is intentionally changed in an experiment or study is called the independent variable. It is manipulated by the researcher to observe the effect it has on the dependent variable.
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.

A controlled experiment is a scientific study in which one variable is manipulated (independent variable) while all others are held constant, to observe the effects on another variable (dependent variable). The purpose is to determine causation between the variables being studied.
The dependent variable is the variable that can change in an experiment.
The dependent variable is the variable that can change in an experiment.
The control group is the group in an experiment that is not exposed to the independent variable being tested. Its purpose is to provide a baseline comparison for evaluating the effects of the independent variable on the treatment group.
