constant
The variable in an experiment that remains the same is known as the control.
A variable within an experiment that remains the same. Such as the weight of a pendulum.
Is known as a constant.
the/a constant.
The control in an experiment is the level of the independent variable that remains the same
A controlled variable is one that remains the same throughout the experiment, i.e., it is not changed
It means that the variance remains the same across the range of values of the variable.
Variable cost per unit remains same with level of production and no change in change in level of production.
Variable cost per unit remains same per unit and has no impact on increase or decrease of sales.
Your question is not clear. The only help that I can offer is this: When all else remains the same, and only the variable changes, this is called "ceteris paribus", which is Latin for "all else remains the same", approximately. So in an experiment you might say, "If we change the variable, ceteris paribus, I anticipate this outcome will occur." Hope this helps.
