A research proposal is another kind of a complicated academic writing you may be asked to complete pursuing a degree. It differs greatly from any other dissertation or thesis sample, as it is a practical proposal on some scientific investigation. It may even be of greater importance to your academia than any other paper you have submitted before. The tricky part in writing your research proposal paper is that it has to be 100% unique and original. No one will analyze a partially plagiarized research proposal, as it is supposed to promote a good start to your future career. Thus, you have to make sure you paper is grammatically flawless, well structured, and plagiarism free.
Qualitative analyses typically require a smaller sample size the quantitative analyses. Qualitative sample sizes should be large enough to obtain feedback for most or all perceptions. Obtaining most or all of the perceptions will lead to the attainment of saturation. Saturation occurs when adding more participants to the study does not result in additional perspectives or information. Glaser and Strauss (1967) recommend the concept of saturation for achieving an appropriate sample size in qualitative studies. Other guidelines have also been recommended. For an ethnography, Morse (1994) suggests approximately 30 - 50 participants. For grounded theory, Morse (1994) has suggested 30 - 50 interviews, while Creswell (1998) suggests only 20 - 30. And for phenomenological studies, Creswell (1998) recommends five to 25 and Morse (1994) suggests at least six. There are no specific rules when determining an appropriate sample size in qualitative research. Qualitative sample size may best be determined by the time allotted, resources available, and study objectives (Patton, 1990).
