Delimitations provide the scope within which researchers conclude findings and determine a studyâs reliability or external validity. Limitations are elements of a study that are not under the control of the researcher. Examples of limitations include funding and time constraints that affect methodology. Limitations decrease the validity of a study, but the research results are still applicable if the researcher discloses limitations and the integrity of the study remains.
