MKF 2121 MINI TASK 4 Yingchao Han 28585070 A Monash researcher wants to recruit 12 unlicensed sex workers to conduct in- depth interviews for a report to better inform policy makers on this issue (for this scenario, just propose a sampling technique. No need to talk about sampling frame or survey method) As the small sample size with 12 and it is an exploratory research, the non-probability sampling technique is appropriate for this situation. Quota sampling is a good choice for the in-depth interview as it is viewed as two-stage restricted judgmental sampling. The first stage consists of identifying segments in the population, and in the second stage, sample elements are selected from each segment based on convenience or judgment. 2. Monash university wants to learn about its students’ attitudes towards the e- learning platform Moodle. The marketing research company commissioned to conduct the research opts to use the survey method for their main data collection. The sampling technique they use is cluster sampling: each faculty—business and economics, medicine, law, engineering and etc—is treated as a cluster. The faculty of Arts and the faculty of Business and Economics are randomly selected as the clusters to be surveyed. From each cluster, the researchers draw a random sample of students to be invited to participate in the survey. Please briefly comment on the sampling technique used. Is it appropriate? If yes, explain why. If not, what would be an appropriate sampling technique for this scenario? No. In cluster sampling, all clusters are homogeneous but within each cluster are heterogeneous. However, in this situation, students within the same faculty are familiar and they are different across faculties. Therefore, the cluster sampling is not appropriate. And the stratified sampling, where all stratas are heterogenous and within each stratum it is homogeneous, is more appropriate technique in this situation.
