The role of a hypothesis in qualitative research is different from its role in quantitative research and grounded theory. In quantitative research, a hypothesis is formulated before the study begins, and it serves as a tentative explanation or prediction of the relationship between variables. It guides the research process by stating the expected outcome and provides a framework for designing the study, selecting the appropriate research methods, and collecting and analyzing data (Neuman, 2014). However, in qualitative research, the role of a hypothesis is different, and its use varies across different qualitative research approaches.
In some qualitative research traditions, such as phenomenology or ethnography, a hypothesis may not be used at all. These approaches focus on understanding lived experiences and social phenomena as they naturally unfold without imposing predetermined ideas or theories (Merriam, 2009). In these cases, the goal is to explore and describe the meaning and context of participants’ experiences or cultural practices rather than test specific predictions.
On the other hand, in grounded theory, a hypothesis plays a crucial role. Grounded theory is an inductive research approach that aims to develop new theories or concepts based on systematically analyzing data. In grounded theory, a hypothesis, called an emerging hypothesis, emerges during the process of data collection and analysis as researchers code and categorize data to identify patterns and relationships (Charmaz, 2014). The emerging hypothesis guides further data collection and analysis, facilitates theoretical sampling, and helps in refining and validating the emerging theory.
The use of a hypothesis in grounded theory helps to provide direction and focus to the research process. Rather than starting with preconceived notions or theories, grounded theory allows theories to emerge from the data and be grounded in the participants’ perspectives. The hypothesis in grounded theory is not based on prior knowledge or assumptions but emerges from the iterative process of data collection and analysis. It is continuously modified and refined as new data is collected and analyzed, leading to the development of more complex and nuanced theories (Charmaz, 2014).
Overall, the role of a hypothesis in qualitative research, particularly in grounded theory, is to guide the research process, provide focus and direction, and facilitate the development of theory. Unlike in quantitative research, where a hypothesis is formulated before the study begins and serves as a testable prediction, in qualitative research, the hypothesis emerges from the data and is continuously revised and refined throughout the research process.

This book by Charmaz provides an in-depth understanding of grounded theory methodology, including the role of hypotheses in the process. It offers detailed guidance on the steps involved in grounded theory research and provides examples and case studies to illustrate the theoretical sampling, data collection, and data analysis techniques used in grounded theory. The author emphasizes the iterative and emergent nature of theory development in grounded theory and how hypotheses play a crucial role in guiding the research process.
In conclusion, the role of a hypothesis in qualitative research differs from its role in quantitative research and grounded theory. In qualitative research, a hypothesis may or may not be used, depending on the specific research approach. In grounded theory, a hypothesis is essential in guiding the research process and facilitating the development of theory. Rather than being formulated prior to the study, the hypothesis in grounded theory emerges from the data and is continuously refined and modified throughout the research process. This allows for a flexible and iterative approach to theory development that is grounded in the participants’ experiences and perspectives.
