Which method is primarily used for qualitative analysis?

Thematic analysis is the method primarily used for qualitative analysis because it involves identifying, analyzing, and reporting patterns or themes within qualitative data. This approach allows researchers to interpret various aspects of the research topic and is particularly suited for exploring subjective experiences, opinions, and emotions. Thematic analysis provides a flexible framework that can be applied across different qualitative research projects, making it a valuable tool for researchers seeking to understand complex social phenomena.

In contrast, other methods listed focus on quantitative data or different forms of research. Statistical analysis deals with quantifying data and applying mathematical theories and models, which is not aligned with qualitative analysis where the focus is on depth of understanding rather than numerical measurement. Data visualization techniques, while useful for presenting data in accessible formats, do not inherently involve analysis but rather focus on the representation of existing data. Experimental research is predominantly associated with testing hypotheses through controlled methods, emphasizing causal relationships and often relying on quantitative data. Thus, thematic analysis distinctly stands out as the core method for tackling qualitative research questions.
