2005). While snowball sampling can be a useful non-probability sampling strategy, its effectiveness is often based in the selection of the initial participants and the degree to which those participants are theoretically random. In recent years, there has...
1). As shown in Table 3, within each community, the same recruitment strategy recruited three separate stakeholder groups who attended the series of three meetings but snowball sampling consistently yielded higher attendance rates to all meetings. Comparison of characteristics of stakeholders who ...
Hence some type of selective sampling strategy is necessary. For example, when searching for holiday accommodation, one could make the search more tractable by only examining reviews of those hotels managed by a popular hotel chain. In this case, the sample is subject to a category frame –...
Discover the different ways you can find a representative sample from a population – and how to choose the best sampling method for your research.
Convenience sampling is a qualitative research sampling strategy that involves selecting participants based on their accessibility and availability to the researcher. Rather than being drawn at random from a bigger population, participants in this strategy are picked because they are easily available to th...
Determining an adequate sample size in qualitative research is ultimately a matter of judgement and experience in evaluating the quality of the information collected against the uses to which it will be put, the particular research method and sampling strategy employed, and the research product intende...
Three key components need to be considered in the sampling strategy: the size of the sample site (i.e., plot size), the sampling pattern, and the number of samples. The plot size generally depends on the variability of the terrain and the application purposes. By default, the plot size ...
When a full list of a larger population is not available, individuals attempting to conduct simple random sampling must gather information from other sources. If publicly available, smaller subset lists can be used to recreate a full list of a larger population, but this str...
