Measurement of concepts

If researcher is using a concept in his study – in quantitative studies, he should be clear about its indicators and their measurement. For example, if researcher plans to measure the effectiveness of an authentic material for learning foreign languages, he must be clear as to what determines effectiveness and how it will be measured. Researcher should not use concepts in his research problem that he is not sure how to measure. This does not mean he cannot develop a measurement procedure as the study progresses. While most of the developmental work will be done during the study, it is imperative that researcher is reasonably clear about the measurement of these concepts at this stage.
