The Researcher's Guide To Sampling: An Overview Of Concepts, Methodologies And Practical Challenges

Abstract

Sampling is one of the fundamental component of the research methodology. It guides the researcher to bridge the gap between theory and empirical populations. It enables researchers to draw conclusions backed by empirical evidence by examining the representative subset of the population. When a researcher executes his research, it is impractical to study an entire population depending on the research objectives, because of many reasons may it be lack of time, resources or a large population, therefore the researcher has to find an appropriate sample size to study the characteristics of the whole population. This paper provides a comprehensive explanation and description of sampling, covering its core concepts, significance both in qualitative and quantitative research, classifications and best practices of sampling in research. This article further discusses the criteria for selecting an appropriate sampling method which follow the research objectives, population, characteristics, sample size, and available resources. It is a quite essential step in research as this stage will determine the conclusion after examination and evaluation of the data collected through sampling, thereby contributing a robust, valid and reliable research study.
