The Variables That do not change in the experiment

A controlled variables are what stayed the same and is compared to other variables
The gender and age should be the same.
It is easier to control independent variables
Model organisms
HTML is not a programming language and as such does not allow you to declare variables.
We Is Doing A Project On Control Variables.
The two types of variables are the CONSTANT and CONTROL.
In an experiment, variables that are not changed are called control variables. These variables are kept constant to ensure that any changes observed in the experiment are due to the manipulated variable, or independent variable, and not due to other factors.
So that you can know what is the manipulating variable, the controlling variable, and the responding variable! To control the variables!
the dependant variable
The control variables.
Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.
control variables: the things that are not changing.Independent variables: the things that you change.Dependent variables: the things that are changed due to the independent variable
