Understanding Sampling Techniques and Determining Sample Size in Qualitative Research. A Novice Guide

Abstract

Purpose: This study aimed to shed light on students and novice researchers on understanding various sampling techniques in qualitative research and the method for determining sample size in qualitative studies. Methods: A narrative design was used to simplify the understanding of the sampling techniques and the method for determining sample size in qualitative research. Together with the use of secondary sources, the researcher's own experience is used to argue and discuss. Findings: The study identified in detail purposive sampling, convenience sampling, snowball sampling, and quota sampling as common sampling techniques for qualitative research. Furthermore, the study pointed out the concept of data saturation as a key determinant of sample adequacy in qualitative research, and it can be affected by factors such as subjectivism, scope of the research, research design, researchers' experience, and data collection methods. Originality: This study expands the methodological literature coverage on qualitative research, which also serves as a guide to both students and emerging researchers in social science research. Practical Implications: This study enhances the common understanding of emerging researchers on the appropriateness of using various qualitative sampling techniques and sample size determination to achieve qualitative study goals.
