🔍 Understanding Qualitative and Quantitative Research

In this paragraph, the distinction between qualitative and quantitative research is explored. Qualitative research is described as focusing on non-numerical data, such as words, concepts, perceptions, and ideas, and is more subjective and exploratory in nature. It is used to gain a deeper understanding of complex situations and to develop hypotheses and theories. Quantitative research, on the other hand, deals with numerical data and is objective, often used to measure differences, relationships, and test hypotheses. The paragraph also introduces mixed methods research, which combines qualitative and quantitative approaches, and explains that these methods are not interchangeable and should be chosen based on the research's purpose.
