c. Stratified 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 stratified sample. Is it answer choice A, Choose 6 employees who volunteer for the study. Answer choice B, assign numbers to all employees, and select every 10th employee. Answer choice C, divide employees into strata based on experience level, then randomly select 3 employees from junior staff and 3 from senior staff, or answer choice D, select the 1st 6 employees who arrive. At work in the morning. So in order to solve this question, we have to recall what we have learned about what a stratified sample is to determine which of the following answer choices describes how to obtain a sample of 6 employees so that the result is a stratified sample. Well, we can recall that a stratified sample is a Sample where the population is divided into distinct subgroups or strata that are based on a relevant characteristic. And once the population is divided, a proportional or equal number of subjects is randomly selected from each stratum. So from the question, we know that the population is the Entire marketing department of a corporation. Well, to make things easier for us, let's assume that the population includes 60 total employees, and we need to divide the population into distinct subgroups such as dividing them into junior employees and senior employees. And since the population in this scenario is 60 total employees, we can have 30 employees in the junior employees subgroup and 30 employees in the senior employees subgroup. And once the population is divided into the distinct subgroups, we can randomly select subjects from each stratum. And so looking at our answer choices, we can identify that answer choices. C is the correct answer, as answer choice C describes how to obtain a sample of 6 employees so that the result is a stratified sample. As we divide the employees into strata based on experience level, such as the junior employees and the senior employees, then we randomly select 3 employees from the junior staff and 3 from the senior staff. So answer choice C is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
