The value of a piece of information that is subject to change during research. It usually occurs in opposition to a fixed constant.

Two terms; “dependent variable” and “independent variable” are utilised in mathematic and statistic subjects.

These Variables are used to define two types of quantities being examined, dividing them into those available at the beginning of a process and those being created by it, when dependent variables are reliant on the former independent variables.
