you are hired by a university to assist in determine the size and range of salary offers for graduating seniors, Describe how you would select a sample of respondents to answer the question of staring salaries and why would you use this particular sample?
To select a sample of respondents to determine the size and range of salary offers for graduating seniors, I would follow these steps:
1. Define the target population: The target population would be the graduating seniors from the university.
2. Determine the desired sample size: The sample size should be representative enough to provide reliable and accurate results. To determine the sample size, I would consider factors like the level of confidence required, desired margin of error, and the available resources to conduct the survey.
3. Choose a sampling method: There are various methods for selecting a sample, such as random sampling, stratified sampling, cluster sampling, or convenience sampling. The choice of sampling method will depend on factors such as the feasibility of reaching the respondents and the desired level of representativeness.
4. Random sampling: For this specific scenario, random sampling would be an appropriate method. Randomly selecting graduating seniors from a list of all eligible students ensures that each student has an equal chance of being included in the sample, making it more representative.
5. Collect data: Once the sample is selected, I would collect data regarding the starting salaries of the selected respondents. This could be done using surveys, interviews, or collecting data from job placement offices or alumni networks.
6. Analyze the data: After collecting the data, I would analyze it to determine the size and range of salary offers for graduating seniors. Statistical analysis techniques like calculating averages, medians, and quartiles can help in understanding the salary distribution.
7. Draw conclusions: Finally, I would draw conclusions based on the analyzed data, presenting information on the average starting salaries, the range of salaries, and any other relevant findings.
By using random sampling, we ensure that every graduating senior has an equal opportunity to be selected, minimizing bias and increasing the representativeness of the sample. This approach allows for generalizations to be made about the entire population of graduating seniors with a certain level of confidence.
