You conduct in-depth interviews with 15 students and ask them open-ended questions such as: How satisfied are you with your studies?, What is the most positive aspect of your study program? and What can be done to improve the study program?.

There are various approaches to qualitative data analysis, but they all share five steps in common: The specifics of each step depend on the focus of the analysis. In the empirical analytical view, researchers adhere to the mind-reality duality and the mind is seen as separate from reality (Hathaway, 1995).

Some examples of quantitative research are: Experimental designs, Non-experimental designs. Methodological assumptions consist of the assumptions made by the researcher regarding the methods used in the process of qualitative research (Creswell 2003). The hypothesis is tested through the analysis and synthesis of the data. (1999). Depending on the discipline, there may be small differences, but the overall framework remains the same. It aims to gather information regarding peoples opinions and views, also to understand peoples values, motivations, perceptions and reactions.

Conclusion 9 References 10 Assumptions Underlying Quantitative Research Introduction Before researchers undertake a research endeavor, it is essential for them to understand the philosophical assumptions that underlie the method of inquiry chosen to answer the proposed research question. Quantitative research is the contrary of qualitative research, in which non-numerical data is collected and analyzed (e.g., text, video, or audio).
