b. Systematic sample

Accepted Answer

Hello everyone. Let's take a look at this question together, and it says, 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 systematic sample. Is it answer choice? A select the 1st 6 employees who arrive at work in the morning. Answer choice B, assign numbers to all 60 employees, randomly select a starting number from 1 to 10, and then select every 10th employee from the list. Answer choice C, choose 6 employees who volunteer for the study, or answer choice D, write all employee names on the slips of paper, and randomly select 6. So in order to solve this question, we have to recall what we have learned about what a systematic sample is to determine which of the following answer choices best describes how to obtain a systematic sample of 6 employees. Well, we can recall that in a systematic sample, the subjects are selected at a fixed interval from an ordered list, in which the first. Subject is chosen randomly and then every case subject is selected afterwards. So in this scenario of the marketing department of a corporation where we need to obtain a sample of 6 employees, we know that our population is, for example, 60 employees in the marketing department of the corporation, and our sample size is the 6 employees. that we need. So we use the formula K is equal to the population over the sample size, and in this case we plug in the values of our population, which is 60 employees and our sample size, which is 6 employees, which gives us K is equal to 60/6, which gives us the value of 10. So now that we have K is equal to 10, we can assign. numbers to all 60 employees, where we randomly select a number between 1 and 10, which provides us with the first subject that we know is chosen randomly, and since every case subject is selected afterwards, we select every 10th employee from that first position. So we can identify that the answer choice that describes how to obtain a sample of 6. Employees, so that the result is a systematic sample is answer choice B. As answer choice B says, we assign numbers to all 60 employees, then we randomly select a starting number from 1 to 10 and select every 10th employee from the list, which would result in a sample of 6 employees. That is a systematic sample, and all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
