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.

• 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
