What is the purpose of theoretical sampling?
Theoretical sampling is a well-known method in grounded theory studies to seek additional data based on concepts developed from initial data analysis. This method involves following where the data have led to expand and refine the evolving theory during the analytical process.
What type of sampling is theoretical sampling?
Theoretical sampling is a form of sampling in qualitative research that is not bounded by the limits of a priori selection. Rather, theoretical sampling entails jointly collecting and analyzing data to decide what data to collect next and where to find them to develop theory (Glaser & Strauss, 1967/2012).
Is theoretical sampling purposive?
Although it is a variation of the purposive sampling, unlike a standard purposive sampling, theoretical sampling attempts to discover categories and their elements in order to detect and explain interrelationships between them.
How does theoretical sampling differ from the generic purposive sampling approach?
Just as with purposeful (or purposive) qualitative sampling, theoretical sampling involves selecting participants based on specific characteristics. The difference between the two lies in the stage at which participants are selected.
What is the difference between purposeful and theoretical sampling?
In purposeful sampling, researchers select the participant sampling criteria prior to conducting research. In grounded theory studies, theoretical sampling occurs as the data collection progresses.
What is the theoretical sampling technique?
Theoretical sampling can be defined as “the process of data collection for generating theory whereby the analyst jointly collects, codes and analyses his data and decides what data to collect next and where to find them in order to develop his theory as it emerges”[1].
Is theoretical sampling probability?
There are two kinds of sampling in social research: statistical – probability or non-probability (when the sampling criteria and the number of participants are established before entering the field according to some rigid sampling rules) and theoretical (when the sampling criteria and the number of participants are …
