Systematic sampling

For instance, a convenience sample may be opportune to obtain, as participants may easily be accessible and available (Frankfort-Nachmias & Nachmias, 2008). However, it may skew the sample, tainting it through introducing sampling bias. As a result, this strategy may not culminate in a representative sample of the population (Frankfort-Nachmias & Nachmias, 2008). Likewise, purposive sampling has the drawback of being based on the subjective judgment of a researcher to obtain a sample (Frankfort-Nachmias & Nachmias, 2008). Since it is impossible to assess the value of a case or determine the researchers motivation for judging samples as representative, the selection may be based on wrongful assumptions and preconceptions about potential participants (Frankfort-Nachmias & Nachmias, 2008). Similar assertions can be made about quota sampling, which will also lead to an inadequate, unrepresentative sample and controversial…

solutions to existing problems. Descriptive research design :> Descriptive research is also called Statistical Research. The main goal of this type of research is to describe the data and characteristics about what is being studied. The idea behind this type of research is to study frequencies, averages, and other statistical calculations. Sample Designing :> After defining the problem . Do work on research design and determine how to collect the data. The next step is to decide who should…

is recommended that researchers identify the methods they used to obtain that sample (Creswell, 2014). Creswell (2014) identified two methods for this process. First, he recommended selecting a random sample (Creswell, 2014). The central characteristic of a random sample is that all individuals have a non-zero and independent chance of being selected to participate (Chamberlain, 2016). Furthermore, randomization allows researchers to better generalize about a population (Creswell, 2016).…

3.2.2 Data collection The investigation is a research method that using self-administered questionnaires or structured interviews that systematic and direct collect data from a sample and study some social phenomenon and rules by analysing statistical data (Saunders 2011). So in order to study the role of social media marketing in the promotion of the Chinese film industry, this research chooses to use the questionnaire to conduct data collection which could be a better a way to know the…

To overcome this problem, we need to provide external validity data for systematic reviews and meta-analyses (Steckler & McLeroy, 2008). I agree with their conclusion that each study has a need for reporting external validity. Thus, there is an argument that “reviews indicate that reporting on external validity is provided far less often than is reporting on other methodological issues” (Steckler & McLeroy, 2008, p.10). In the same regard, Glasgow et al. (2004) addressed the same issue that “in…

This list shows the customers who have been banking with them both past and present. This will give the sampling method a larger pool to gather information to complete the research needed. What is the appropriate sampling size? The appropriate sampling size is achieved by many factors. These factors are the size of the study, population size, the purpose of the study, and the risk of selecting a wrong sample design. The size of the sample must be in a certain criteria such as precision level,…

The authors used focus groups which allowed the African-American students to share their racial climate experiences on their college campuses using a critical race theory (CRT). A grounded theory approach was used to investigate the concepts of racial microaggressions and the college racial climate. Transcripts, research memos, and field notes from the data which allowed systematic analysis of the thematic patterns to emerge from the data that was collected (p. 65). The focus group analysis…

Critical analysis is defined as a systematic evaluation utilized to recognise the strengths and weaknesses of a scientific article in order to assess the usefulness and validity of research results.1,2 It is an essential skills that all researchers should have in order to distinguish deceptive information and filter out any low-quality research.3 The purpose of this paper is to critically analyze a scientific research article entitled “Time to manage: patient strategies for coping with an…

The data will be collected, measured, and a report generated based on results from within each age group and for the total population. The results will be order ranked for each age group and for the entire population. The method captures the same data from all participants, regardless of age. The data can then be used to generate statistical information and correlated to find patterns of differences and/or similarities. Sampling Techniques A random sampling technique of proportional…
