Discussion 1 week 3 prior to beginning work on this discussion forum, read Chapter 7: Sampling and Sampling Distributions. For your initial post, Provide an example of when you might want to take a cluster random sample instead of a simple random sample. an example in a business situation could be where you need to evaluate how satisfied workers are in different divisions within a big organization. You can decide to use a cluster random sample as an alternative to choosing random personnel from the whole organization to conduct a basic random sample. The company is divided into departments in this instance, and each department is a cluster. You choose at random a few departments and survey each staff member in those departments as opposed to surveying every employee in the organization. This method is more feasible and practical than attempting to speak with each employee on an individual basis. You can still obtain accurate information about employee happiness by employing cluster random sampling, which also saves money and logistical difficulties related to polling all staff members in the company. rather than asking every worker in a poll. In a commercial setting, it makes data collection more practical and effective. Explain what the advantages of a cluster sample might be. The use of cluster sampling has benefits as well as disadvantages. Convenience and cost are among the primary benefits (Albright and Winston, 2020). Cluster sampling has advantages such as efficiency, as it's more practical for large populations, saving time and resources. It ensures representativeness by focusing on naturally occurring groups, reflecting population diversity. This method is practical when the population is widespread, avoiding logistical challenges and costs. Additionally, it's beneficial when studying similar characteristics within clusters, making sampling more efficient. For instance, in testing a new teaching method, it's more practical to sample entire classrooms (clusters) than individual students. Overall, cluster sampling streamlines the sampling process, providing reliable insights while addressing practical considerations in research. Explain how you would choose the cluster sample. To select a cluster sample First, define the population to select a cluster sample based on test results. Following that, divide people into groups according to their test results. Clusters should be chosen randomly to ensure representation across a range of score values. Add all the individuals in the selected clusters to the sample. A thorough examination is made possible by this method's ability to collect a wide variety of test performance levels within the population Discussion 2 week 3
