Final answer:
The statement is true; grounded theory analysis does use a constant comparative method. This is part of a wider approach in qualitative research where data guides theory development, and various methods are valid in scientific investigations.
Step-by-step explanation:
Grounded theory analysis indeed involves the use of a constant comparative method. This method consists of systematically comparing elements of data, codes, and categories in qualitative research to develop a well-supported ground theory. General theories must align with existing data and theories to be sustained, signifying that a theory remains valid as long as it is not refuted by new data. In this context, data that does not support a hypothesis can still be useful because it shapes the refinement or rejection of that hypothesis.
Furthermore, experimentation is just one type of valid scientific investigation among many, including interviews, surveys, and comparative historical secondary data analysis. In the scientific community, the acceptance of a theory depends on how well it integrates into the existing conceptual framework, even as all observations are considered theory-laden.
