d. Cluster sample

d. Cluster sample

Accepted Answer

Hello everyone. Let's take a look at this question together. Presume that everyone who works in the marketing department of a corporation is included in the population. Describe how to obtain a sample of 6 employees so that the result is a cluster sample. Is it answer choice A? Choose 6 employees who volunteer to participate in the study. Answer choice B, assign numbers to all employees, and select every 10th person from the list. Answer choice C, divide employees into junior and senior levels, then randomly pick 3 from each level, or answer choice D, divide the employees into 10 teams of 6, assign numbers to each team, select 1 team using a random number generator, and include all 6 employees from that team in the sample. So in order to solve this question, we have to recall. What we have learned about what a cluster sample is to determine which answer choice describes how to obtain a sample of 6 employees so that the result is a cluster sample. Well, we can recall that a cluster sample is where the population is divided into groups or clusters that are similar to each other, and entire clusters are. randomly chosen. So looking at the question, we must first define our population, which we can define the population as, say, 60 employees in the marketing department, and suppose the 60 employees are divided into 10 teams, which are the clusters containing 6 employees each. So to obtain a sample of 6 employees so that the result is a cluster. Sample from our population, we can assign each team or cluster a number from 1 to 10, and then use a random number generator to select a team where the team corresponding to the selected number is chosen. So then the sample includes the 6 employees from that selected team. Therefore, the answer choice that describes how to obtain a sample of 6. Employees so that the result is a cluster sample is answer choice D. As answer Choice D says, divide the employees into 10 teams of 6, assign numbers to each team, select a team using a random number generator, and include all 6 employees from that team in the sample, which gives us a cluster sample, and all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
