Of the 51 studies, 11 contained a discussion of saturation and achieving saturation. Aside from that study, no pattern between sample size and duration of interviews was evident among the studies. British Medical Journal, Vanclay, Jerome K. The purpose of this kind of sample design is to provide as much insight as possible into the event or phenomenon under examination.
I will use a nonprobability (purposive) sampling technique. Realizing that a Looking for calculation method and/or literature, studies that may provide insight. Thank you.

Concerning your issue about the calculation of the exact sample size for non random sampling. Calculating the right sample.
Punched card 20 Purposive sampling Rectangular distribution Regression–coefficient –curve, –equation –line.
Educational Researcher39 5 Typical Case Sampling. A key qualitative feature is that research questions are typically limited, studying a central phenomenon in a particular context.
They used each phase of the study to add additional data, assess for saturation, and ultimately achieve saturation. Karamustafaoglu, Orhan However, before discussing sample sizes further, it is necessary to discuss sampling generally, and although we should resist the urge to think about qualitative sampling from a quantitative viewpoint EMMEL,it is helpful to compare the two approaches.
. If the sample size is less than 30, the value of k in the formula for the lower and 4. A purposive sample is one that is selected based on characteristics of a population and the purpose of the study. Learn more about it. However, determining the ideal survey sample size and population can prove. Calculate your own sample size using our online calculator Can you please help me calculate the sample size for purposive sampling with formula?
Example: Total respondents from two (x and y groups) are =
In instances when the group size was a realistic number to interview or include in focus groups, the researchers generally seemed to include the entire group within the sample. A homogeneous purposive sample is one that is selected for having a shared characteristic or set of characteristics.
