The specific way in which a variable is measured in a particular study is called the operational definition. It is critical to operationally define a variable in order to lend credibility to the methodology and to ensure the reproducibility of the results. Another study may measure the same variable differently.
Research begins with WHAT you want to find out, not how you plan to discover it. 1  Conceptual variables are about abstract constructs; operational variables (operational definitions) are the concrete operations, measures, or procedures used to measure the concept in practice. A confounded variable is multidimensional, it is a variable in which several variables are simultaneously embedded.
