Final answer:
To conduct a representative sample of deep coal miners for a survey on safety in the deep coal mines, Devon should follow a systematic approach. This includes identifying the population, selecting a sample size, choosing a sampling method, contacting the miners, and conducting the survey.
Step-by-step explanation:
In order to conduct a representative sample of deep coal miners for the survey on safety in the deep coal mines, Devon should follow a systematic approach. Here are the steps Devon should take:
- Identify the population: Devon needs to determine the target population for the survey, which would be deep coal miners.
- Select a sample size: Devon should determine the appropriate sample size that would provide a representative representation of the population. This can be done using statistical formulas or consulting with experts.
- Choose a sampling method: There are different sampling methods that Devon can use, such as simple random sampling, stratified sampling, or cluster sampling. Devon should select a method that best suits the research goals and limitations.
- Contact the miners: Devon can reach out to coal mining companies or organizations to gain access to the deep coal miners. It is important to ensure that the participants are willing to participate and that their safety is prioritized.
- Conduct the survey: Devon should administer the survey to the selected sample of deep coal miners. This can be done through face-to-face interviews, phone surveys, or online questionnaires.
By following these steps, Devon can obtain a representative sample of deep coal miners and gather valuable data about safety in the deep coal mines.
