Converting Concepts into Variables
If you are using a concept in your study, you need to consider its operationalization – that is, how it will be measured.
Operationalization of concepts is the process of defining and quantifying abstract concepts so that they can be measured and studied in a research or scientific context.
It involves turning abstract ideas or theoretical constructs into specific, observable, and measurable indicators or variables.
In many fields, especially in social sciences and empirical research, researchers often deal with abstract concepts that cannot be directly measured. Operationalization provides a clear and concrete way to transform these abstract concepts into observable and measurable variables, making them amenable to data collection and analysis.
In most cases, to operationalise a concept you first need to go through the process of identifying indicators – a set of criteria reflective of the concept – which can then be converted into variables. The choice of indicators for a concept might vary with the researcher but those selected must have a logical link with the concept. Some concepts, such as ‘rich’ (in terms of wealth), can easily be converted into indicators and then variables. For example, to decide objectively if a person is ‘rich’, one first needs to decide upon the indicators of wealth.
Assume that we decide upon income and assets as the indicators. Income is also a variable since it can be measured in dollars; therefore, you do not need to convert this into a variable. Although the assets owned by an individual are indicators of his/her ‘richness’, they still belong to the category of concepts. You need to look further at the indicators of assets. For example, house, boat, car and investments are indicators of assets. Converting the value of each one into dollars will give the total value of the assets owned by a person. Next, fix a level, based upon available information on income distribution and an average level of assets owned by members of a community, which acts as the basis for classification. Then analyse the information on income and the total value of the assets to make a decision about whether the person should be classified as ‘rich’. The operationalisation of other concepts, such as the ‘effectiveness’ or ‘impact’ of a programme, may prove more difficult.
One of the main differences between quantitative and qualitative research studies is in the area of variables. In qualitative research, as it usually involves studying perceptions, beliefs, or feelings, you do not make any attempt to establish uniformity in them across respondents and hence measurements and variables do not carry much significance. On the other hand, in quantitative studies, as the emphasis is on exploring commonalities in the study population, measurements and variables play an important role.

What is Operational Definition of Variable?
An operational definition of a variable is a clear and specific statement that defines how the variable will be measured or manipulated in a particular study or experiment.
It provides a practical description of the variable in terms of the procedures or operations used to observe or manipulate it.
The purpose of an operational definition is to make the variable measurable and replicable, ensuring that other researchers can use the same definition to conduct similar studies.

Operationalization is the broader process of transforming abstract concepts into specific variables, while an operational definition is a specific statement that defines how a variable will be measured or manipulated in a particular study. Operationalization is a more general concept applicable to the overall research process, while operational definitions are specific to individual variables within a given study.
