The Role of Concepts in Research
Concepts play a key role in the development of hypotheses. Concepts are the basic building blocks of hypotheses: For example, a hypothesis such as 'education increases income' specifies a positive relationship between the concepts 'education' and 'income'. To test this, researchers find a way to measure these concepts. For example, 'education' could be measured by 'years of school or highest degree completed'. Income could be measured by 'monthly salary' or salary received each year. Unless researchers can find ways to measure the concepts they are studying, they will not be able to confirm their hypotheses.
