Importance of identifying the different variables in research
A variable is defined as a property that can assume a type of measurement and be assigned different values of the measurement. It is vital to identify the nature and type of a variable to understand the relationship between the concepts that are being measured (Jisunge Educational Programme, 2010). Additionally, the identification of the type of variable applicable in the research process plays a vital role in the valid and accurate determination of results and findings and the subsequent interpretation.
Implications of variables to the research process
The application of the use of the different types of variables to fit the specific requirements of a research points to the comprehensive nature of the research process. Furthermore, the selection of the variables to be used in accordance with the concepts being measured enhances the validity and accuracy of the analysis of the results collected by researchers (Jisunge Educational Programme, 2010). In addition to this, researchers point to the fact that variables and the concept of measurement have made various social, economic, and political concepts quantifiable (Jisunge Educational Programme, 2010). The ability to measure concepts positively contributes to the establishment of linkages between theoretical research and the application of concepts to the society at large.

Examples of how variables are defined and measured.
Variables are mainly defined as measurable variables and immeasurable variables. Measurable variables can also be termed as quantitative variables and are identified by the continuity of the concepts being measured (Jisunge Educational Programme, 2010). For instance, discrete variables refer to variables that can be assigned a numerical value and are specified in quantity (Jisunge Educational Programme, 2010). An ideal example of a discrete variable would be the number of cars that arrive at a carwash at a given day. The number observed can only be identified as a finite number, for instance, 7 cars. On the other hand, continuous variables even though quantifiable are abstract in nature and lack a discrete end. An example of a continuous variable would be weight given the fact that weigh can be measured infinitely, depending on the weight of an object (Jisunge Educational Programme, 2010). Given that the variables are quantifiable, they are accorded specific measurements in terms of kilograms for weight and numeric for the number of vehicles recorded in a carwash.
