Delimitations and limitations clarify the boundaries, exceptions, and reservations inherent in every study. The two concepts are different in that:
Delimitations aim to narrow the scope of a study. For example, the scope may focus on specific variables, specific participants, specific sites, or narrowed to one type of research design (e.g., ethnography or experimental research).
Limitations, however, aim to identify potential weaknesses of the study. For example, all statistical procedures and research strategies, such as surveys or grounded theory studies have limitations. In introductory discussions about these strategies, authors typically mention both their strengths and their weaknesses.
However, in journal articles, researchers incorporate delimitations into the methodology section, and they write limitations into the final section of their studies.
