This type of sampling, also known as judgement sampling, involves the researcher using their expertise to select a sample that is most useful to the purposes of the research. Similar to a convenience sample, a voluntary response sample is mainly based on ease of access. Samples are used to make inferences about populations. Inclusion and exclusion criteria are determined after formulating the research question but usually before the search is conducted (although preliminaryscoping searches may need to be undertaken to determine appropriate criteria). Exclusion Criteria Exclusion criteria are the elements of an article that disqualify the study from inclusion in a literature review. Sampling bias occurs when some members of a population are systematically more likely to be selected in a sample than others. Probability sampling means that every member of the population has a chance of being selected. The number of individuals you should include in your sample depends on various factors, including the size and variability of the populationand your research design. .
