Sampling Methods




Whenconducting a study, researchers may use their family members asrespondents. This is called convenience sampling. For example, whenobserving the correlation between children’s homework and theirgrades, it would be convenient to recruit a relative`s kids since itwould be easier to obtain permission to carry out the study. However, there are various challenges linked to this type of study.First, when collecting data, the researchers may experienceuncontrollable factors that emanate from their relationship with theparticipants (Emerson, 2015). For example, the relatives may beliving in the same location, and this would introduce a geographicalbias. Secondly, some studies are sensitive, and they are bettercarried out on anonymous subjects. The ethical component of includingfamily members in a study may result in betrayal and discomfort whensharing information (Brewis, 2015). Besides, relatives may not givetruthful responses, and they may only participate to please theresearcher (Bryman &amp Bell, 2015). According to Brewis (2014),friends and relatives may feel being reduced to study objects.Therefore, researchers should weigh the ethical considerations whilecarrying out a snowball study.


Duringstudies, researchers use samples due to resource, time and accesschallenges. Selecting a population that represents the truecharacteristics of the population is imperative in any study.According to Gracvetter and Wallnau (2016), various factors influencethe sample size of any given study. They include the margin oferror, size of the population, probability of selecting a certainresponse, effect size and the strength of detecting the implications(Walker et al., 2016). These factors determine the credibility of aresearch and its ability to be applied in different settings.

Thetarget population for my study includes ICT undergraduate students ina research university in the South West of the United States. Thesample was arrived at through purposeful sampling. The GPoweranalysis was used to settle on an ideal sample of 82 to 134participants. It was calculated using Alpha level = .05, Beta = .80and .95, and effect size = .3 (Bach et al., 2012). After collectingthe questionnaires issued to the respondents, I will compile andanalyze the data using a combination of descriptive statistics. Iwill employ the frequency statistics to summarize the number ofstudents who look forward to starting a new business and those who donot have such ambitions.
