Characteristics that limit the scope and describe the boundaries of the study, such as the sample size, geographical location or setting in which the study takes place, population traits, etc. Additionally, the researcher might also choose to use some research tools and methodologies to collect data but not others. These delimitations might be imposed for practical reasons such as lack of time or financial resources to carry out a more thorough investigation. The delimitation section of the study should explain why specific choices were made while others were excluded and how this might affect the outcome of the research.
