Sampling, reliability, and validity of your research proposal.

Posted on | by Brian Leakey | Leave a Comment on Sampling, reliability, and validity of your research proposal.

 

 

focus on the sampling, reliability, and validity of your research proposal. This section will include information on sampling, reliability, and validity.
The following components should be addressed in your paper this week:
Information on your sample
• Sampling basic information (age, gender, criteria, etc.)
• Sample size
• Explain why your sample is appropriate for your study
Reliability
• Explain how your data collection process is consistent and reliable
• Explain why your measurement tool is reliable
Validity
• Explain how you will ensure you have a valid sample
• Explain how you tested the validity of your measurement tool

Sooyan wants to study perceptions of sports advertising on a college campus. The student body at this university is 60% female and 40% male. He advertises for his study and there is a strong interest among the student body. He obtains statistically significant results and is looking forward to publishing them. However, after he has finished his study and two days before his project is due, he realizes that his sample included 70% males and 30% females.

In reference to the above scenario, answer the following questions:

Does this represent proper quota or stratified sampling?
What do you think Sooyan should do?
List three research strategies each, you can use to follow both quota and stratified sampling.
Using the South University Online Library, find and summarize three articles. Focus on the methods they used to ensure representation.
Do you think any of these methods are also applicable in research involving animals?

As you might expect, it is impossible to study the entirety of any particular population. However, researchers can collect data for their studies from a sample of that population. The characteristics of the sample are important for generalizability—the extent to which research findings can be applicable to a larger population. To support generalizability, the sample should be as much like the population as possible and a large enough size to mitigate the chance of differences.
This week, you explore sampling and select a sampling technique for your research. Additionally, you begin to compile information and plans for your proposed study into a formal research proposal. Part 1 is due this week, and you will submit Part 2 next week.
Learning Objectives
Students will:
• Identify the population and sample for a proposed research study
• Analyze the needs of the research study to determine an appropriate sampling method
• Analyze ethical and cultural considerations related to research study population
