Theoretical sampling helps in exploring various hibernating research questions that are eventually evident in the data collection as a theory. According to Glaser and Holton (2004), Grounded theory that has a data collecting inclination towards theoretical sampling was first derived from qualitative sampling.
Sampling methods may be either random (random sampling, systematic sampling, stratified sampling, cluster sampling) or non-random/nonprobability (convenience sampling, purposive sampling, snowball sampling). [3] The most common reason for sampling is to obtain information about a population. Sampling is quicker and cheaper than a complete ...
Interpretative phenomenological analysis (IPA) is a qualitative form of psychology research. IPA has an idiographic focus, which means that instead of producing generalization findings, it aims to offer insights into how a given person, in a given context, makes sense of a given situation.

The subset is meant to reflect the whole ...
Rather than relying on predetermined formulas or statistical calculations, it involves a subjective and iterative judgment throughout the research process. In qualitative studies, researchers often adopt a subjective stance, making determinations as the study unfolds. Sample size determination in qualitative studies takes a different approach.
