Dr. Jones wants to study nurses' attitudes toward end-stage cancer patients. What kind of sample can he use for his study?

In this scenario, a convenience sample of available nurses is a practical choice for Dr. Jones's study on attitudes toward end-stage cancer patients. Convenience sampling involves selecting participants who are readily accessible and willing to participate, making it a cost-effective and efficient method, particularly when time and resources are limited.

Nurses who are available may already be in the right setting to express their attitudes based on direct interactions with end-stage patients. Using a convenience sample allows Dr. Jones to gather data quickly and without the complexities of coordinating with a larger population or sampling from different locations.

While random samples and stratified samples offer the advantage of reducing bias and ensuring representation across various demographics, they may require more resources and planning. A paired sample, on the other hand, would focus on matching nurses with specific patients, which does not align with the goal of solely understanding nurses' attitudes. Thus, opting for a convenience sample enables Dr. Jones to gather insightful data promptly from those in close proximity to the subject matter.
