Technique of Developing Measurement Tools:
a) Concept development: This is the first step. In this case, the researcher should have a complete understanding of all the important concepts relevant to his study. This step is more applicable to theoretical studies compared to practical studies where the basic concepts are already established beforehand.
b) Specification of concept dimensions: Here, the researcher is required to specify the dimensions of the concepts, which were developed in the first stage. This is achieved either by adopting an intuitive approach or by an empirical correlation of the individual dimensions with that concept and/or other concepts.
c) Indicator selection: In this step, the researcher has to develop the indicators that help in measuring the elements of the concept. These indicators include questionnaires, scales, and other devices, which help to measure the respondents opinion, mindset, knowledge, etc. Using more than one indicator lands stability and improves the validity of the scores.
Index formation: Here, the researcher combines the different indicators into an index. In case, there are several dimensions of a concept the researcher needs to combine them.
