Final answer:
The saturation point in qualitative research indicates when a researcher should leave the field to start data analysis, coming when further data collection no longer contributes new insights.
Step-by-step explanation:
The saturation point is the cue to the researcher to leave the field of study and begin analyzing data.
In qualitative research, the saturation point refers to the moment when additional data does not provide any new insights or understanding of the research question. At this stage, the researcher has collected enough data to fully explore the concepts and phenomena of interest, making it an appropriate time to exit the field and move on to data analysis. This concept is important as it ensures that research time and resources are used efficiently while still achieving a thorough understanding of the subject matter.
