Research Methodology: A Project Guide for University Students – Assignment Example
The paper "Research Methodology: A Project Guide for University Students" is a worthy example of an educational assignment.
The problem identified in the sampling plans of the articles rotates around three issues. One is getting a population sample that is representative enough. This ensures that the information gathered is accurate. The second issue is on time. The sampling design should not take too much time to get the required information as this makes it more expensive. The last concern is related to costs, the sampling design used should be cost-effective. The benefits obtained from the research should be more than the costs concerned.
The problem of proper representation can be overcome by using the stratified sampling method that ensures that members of all important subsets in the population are involved. The confidence level and confidence intervals are determined as a way of setting the deviation of data collected from that of the actual populations. The issue of time can be dealt with by using both observational and historical material to get data on a certain population. Getting empirical information on a large number of population samples is involving in terms of time and labor (Kuada 2012). The empirical data obtained should be supplemented by historical data obtained from the library that is easy and cheap to access. The makes the overall information used in the study wholesome and lessens the time needed to collect information. Getting a representative population sample may be expensive depending on the method of collecting data used. In order to reduce costs for a research designed to get responses from the sample population, cheap methods such as emailing can be used instead of the traditional one on one interview. Emails reach a large number of people simultaneously and are relatively cheap. However, they have a higher likelihood of being ignored (Kuada 2012). A large sample of respondents should be picked so as to get enough responses to work one.
