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 mediating variable is intermediate in the causal relationship between two variables such that an independent variable causes the mediating variable which causes a dependent variable.Mediating variables are important in a number of fields because they explain how and why two variables are related.ediating variables in prevention serve a different purpose than other applications of mediating variable methodology. In the prevention case, mediating variables are selected before the study and are fundamental to the prevention program because of their causal relationship to the dependent variable.
