In qualitative research, what is saturation?

• A. The point in qualitative research where no new information arises.
• B. The maximum statistical power of a test.
• C. The highest degree of measurement precision.
• D. The reliability coefficient of a coding scheme.

Answer: (A)

Saturation is the point in qualitative research at which gathering additional data stops adding new information, ideas, or themes. As you collect and analyze data—reading interviews, coding passages, and comparing patterns—you build a set of codes and categories. When you keep encountering the same themes and no new codes or insights emerge, you’ve likely reached saturation. This means you’ve explored the topic enough to understand the range of experiences or perspectives relevant to your questions, and further data collection is unlikely to change the analysis. It’s not about statistical power, measurement precision, or a coding reliability coefficient—those are quantitative concepts. Saturation focuses on depth and completeness of understanding in the qualitative sense.
