Sampling Methods in Research Methodology; How to Choose a Sampling Technique for Research. In order to answer the research questions, it is doubtful that researcher should be able to collect data from all cases. Thus, there is a need to select a sample. This paper presents the steps to go through to conduct sampling.

There are already some helpful overviews of sampling in textbooks on research methodology (see, e.g., Gray et al, 2007; Bryman, 2008), which discuss ideas covered in this paper in more detail. The aim of this paper, though, is to provide an introduction to some key concepts and approaches to.
Further, the numerous technique options outlined above make purposive sampling a versatile research method that can be tailored to enhance a study’s effectiveness. Sometimes purposive sampling may be the only appropriate method available if there are a limited number of primary data sources that can contribute to the study.
Simple random sampling (also referred to as random sampling) is the purest and the most straightforward probability sampling strategy. It is also the most popular method for choosing a sample among population for a wide range of purposes. In simple random sampling each member of population is equally likely to be chosen as part of the sample.
