Sampling Strategy and Sample Size for a Qualitative Research Plan
A grounded theory perspective on the victimization of women and human trafficking
The formulas for determining appropriate sampling sizes for quantitative research studies are fairly formalized, given the need to make generalizations about the macro-level population based upon the findings of these experimental or quasi-experimental studies. However, the purpose of qualitative studies is to come to conclusions based upon the researcher's inductive findings regarding a specific group of people. For an ethnographic study, the 'sample size' of the population might constitute a very small tribe. A narrative qualitative study might involve discussing the findings of studying a small class of children. The purpose of qualitative studies is to let the experiences of individuals speak for themselves, whether this takes the form of a case study, a narrative of a specific handful of participants, or simply 'making meaning' from a culture. Although I would hope that my grounded theory study on women who had been trafficked into the sex trade or economic slavery would yield findings that would be helpful in giving assistance to such women in the future and contribute to my reader's general understanding of the topic, my ultimate purpose is still to let these women speak, and the theory will derive from their experiences. My hypothesis as a researcher should not drive and shape the findings.
In general, with quantitative research, larger sampling sizes are preferable, given the 'law of large numbers' or the idea that large samples are less prone to exhibit errors because of anomalies. But "there is a point of diminishing return to a qualitative sample -- as the study goes on more data does not necessarily lead to more information. This is because one occurrence of a piece of data, or a code, is all that is necessary to ensure that it becomes part of the analysis framework" (Mason...
Sampling Strategy and Sample Size for Quantitative Research Plan Referred to as modern-day slavery, the criminal and devastating incidences of human trafficking is something that are of responsibility of the entire international stage. This paper will look at the global emergency of human trafficking and will seek to examine the best method of gathering a sample for a quantitative research study. This research study seeks to accumulate the most relevant and
Sampling Strategy and Sample Size for a Quantitative Research Plan [To what extent do African-American men who live in an urban setting and exhibit aggressive behavior due to early development factors associated with depression receive a diagnosis at local medical facilities of conduct disorder as opposed to depression?] The question posed in this study is one asking 'To what extent do African-American men who live in an urban setting and exhibit aggressive
Sampling Strategy and Sample Size in a Research Article The study by Choi (et al. 2008) entitled "The efficacy of female condom skills training in HIV risk: A reduction among women: A randomized controlled trial" examined the extent to which training women in how to use the female condom at family planning clinics could potentially promote the use of this form of birth control. The study population was selected from
Sampling Plan Before discussing a sampling plan, there has to be clear and unambiguous definitions of what a sample and sampling are. Despite diversity in the definition of a sample, the best meaning is that a sample could be considered as a subset of a population, with which a researcher would like to use as participants in a given research study (Landreneau & Creek, 2012). According to Deming (1990), sapling is
Sampling Size: Qualitative Research The aim of qualitative research is to ensure that the population in question is studied with sufficient rigor and above all sufficient depth to yield meaningful results. "There is a point of diminishing return to a qualitative sample -- as the study goes on more data does not necessarily lead to more information… qualitative research is concerned with meaning and not making generalised hypothesis statements" (Mason 2010:8).
Social Network Survey Draw a sample The sample for this study utilizes non-probability sampling techniques. Unlike probability sampling, nonprobability sampling does not use random selection (Trochim, 2006). Random selection is rarely used in qualitative survey research as the population will have been selected for specific purposes and often a certain level of attribute representation is desired in the sample for purposes of analysis. Because distinctions between the responses of survey participants from
