Defining Variables. Variables can be defined as any aspect of a theory that can vary or change as part of the interaction within the theory. In other words, variables are anything can effect or change the results of a study. Every study has variables as these are needed in order to understand differences.here is no limit to the number of variables that can be measured, although the more variables, the more complex the study and the more complex the statistical analysis. The most powerful benefit of increasing our variables, however, is control.
A variable plays a role on the mediator variable under some specific conditions. The conditions of being the mediator variable are as follows: If the change in the level of the independent variable significantly accounts for variation in the other variable, then the variable is considered a mediator variable.n other words, it explains the relationship between the dependent variable and the independent variable. The process of complete mediation is defined as the complete intervention caused by the mediator variable.
