How do you explain variable change?

In mathematics, a change of variables is a basic technique used to simplify problems in which the original variables are replaced with functions of other variables. The intent is that when expressed in new variables, the problem may become simpler, or equivalent to a better understood problem.

Which is the changing variable?

The independent variable is the one that is changed by the scientist.

What is the changing of variable parameters?

The changing of variable parameters is called as variation. In problems relating to two or more variables, it is seen that the value of a variable changes with the change in the value ( or values ) of the related variable (or variables).

What refers to change in one variable due to change in other variable?

correlation - Relationship between change in one variable in relation to another - Cross Validated.
