This article considers and explains the differences between the two approaches and describes three broad categories of naturalistic sampling: convenience, judgement and theoretical models. To draw a convenience sample, we would simply collect data from those people or other relevant elements to which we have the most convenient access.

An approach to sampling, common in qualitative research, that chooses subjects that will provide insight for answering the study questions. Finally, convenience sampling is another nonprobability sampling strategy that is employed by both qualitative and quantitative researchers. Criterion Sampling. Most quantitative studies follow these steps: 1) Select the target population, 2) Select the accessible population, 3) State the eligibility criteria, 4) Outline the sampling plan, and 5) recruit the sample. •This will not be achieved through superficial knowledge about a large, representative sample of individuals.

Most qualitative studies might evolve this way: 1) a general idea of where and with what population to start and by soliciting a few cases through convenience procedures, 2) … The difference in sampling strategies between quantitative and qualitative studies is due to the different goals of each research approach.Recall that typical quantitative research seeks to infer from a sample to a population (for example, a relationship or a treatment effect).. What are the different sampling methods in quantitative research? Convenience sampling (also known as availability sampling) is a specific type of non-probability sampling method that relies on data collection from population members who are conveniently available to participate in study. However, randomly selecting people from a large population is still a desirable approach in some qualitative research. It would be ideal to test the entire population to gather results, but that work is almost impossible when trying to include each person. Itmeans, sampling to the point at which the researcher recognizes no new information is obtained from the participants and data on all dimensions of an emerging category is generated (Glaser, 1978).
