Qualitative Studies - Essay ExampleTherefore, the discussions and observations are structured loosely, thus allowing for the looking at of a full range of beliefs, feelings, and behaviours (Polit and Beck, 2007, 57). However, in contrast to quantitative studies, analysis and interpretation are ongoing and concurrent activities that will continue to guide choices close to the next sample with concurrent modifications of the types of questions or necessary observations. Thus with the goal of clustering together of related types of narrative information into a coherent lineation of time consuming and intensive data analysis, the sample needs to be determined.The aim of most qualitative studies is to discover meaning and to uncover multiple realities, and so generalizability is not a guiding criterion as in quantitative studies. Thus probability sampling is not necessary. Randomly selected population may not necessarily be good informants, and thus the sampling method must be one of n onprobability methods. These include extreme or deviant case sampling, normal case sampling, and snowball sampling (Cochran, 1977, 13-47). This means, there must be a purpose for any particular sampling method. In probability sampling, elements are selected by nonrandom methods. ... These are convenience, quota, and purposive (Polit and Beck, 2007, 292).Convenience SamplingA convenience sample can be defined as a sample in which seek subjects are recruited based on their ease of availability, or in other words, the sample comprises of the most conveniently avail equal subjects. Essentially, individuals who are the most ready, willing, and able to participate in the study are the ones who are selected to participate. In qualitative research, it may be helpful to use a convenience sample to hear the appropriateness of interview questions. This is an inexpensive and quick way to test the design of the study by approaching an matter toed group of people first in the lead embarking on a larger, longer, and more expensive study (Diekmann & Smith, 1989, 418-430). The main problem with such sampling is that the available subjects might be atypical of the population of interest with regard to critical variables. It has been argued that convenience samples can lack transferability or external validity in qualitative research. Thus although this is simple and more cost-effective, it is important to esteem that the participants recruited are not necessarily reflective of the population being studied, and they may not necessarily be reflective of all view points, and thus the research may be criticized to be biased (Polit and Beck, 2007, 292).Quota Sampling (Stratified Purposeful)This is also known as quota sampling in which the researcher identifies population strata and also determines the number of participants inevitable from each stratum. To be able to determine this, the information about the population characteristics is necessary, since it should represent d iverse segments preferable in a representative
