Create the operational definitions so another researcher can understand and assess your definition of the abstract concepts. Limit your definitions to one sentence each.
Example: For purposes of this study, schooling is defined as the number of completed grade levels in public education institutions. For purposes of this study, pay off is defined as an increase in income level.
