What is data saturation and why is it important in research?

Data saturation refers to the point in qualitative research when no new information or themes are emerging from data collection. It's crucial because it ensures that the data collected is comprehensive and reliable.

How do researchers determine when they've reached data saturation?

Researchers typically determine data saturation by analyzing the data collected during interviews or focus groups. They look for repetitive themes and stop collecting data when they notice that new interviews yield similar insights.

Can you give an example of a study that illustrates data saturation?

Sure! In a study exploring patient experiences in healthcare, researchers might conduct interviews until they find that additional interviews do not reveal any new insights about patient satisfaction.

What happens if a researcher stops collecting data too early?

If a researcher stops too early, they risk missing important insights, which can lead to incomplete or biased findings. This can ultimately affect the validity of the research.
