Limitation in research is the lack of adequate information on a given subject due to variables. Limitation in research most often applies to academic research; however, there is limitation to all forms of research because it is impossible to control all variables. For example, a study conducted in only one city and involving only women has limitations that include gender, sample size and location. Additionally, all research is limited by the perception of the researcher.
There are two types of research methods: qualitative and quantitative. Both research methods involve gathering information on a subject. Qualitative research is used most often in the social sciences to study people, behavior, language and culture. Examples of limitations in qualitative research include the number of participants in the study and the scope of the research.
Quantitative research methods are used in scientific research and in some disciplines, such as economics. This kind of research involves quantifying, or measuring, a given subject, Scientific research involving medication is most prone to limitations. This is due to the fact that participants have different medical histories, health conditions, ages and so on that affect how they react to the drug. These factors are all considered to be limitations.
