Which is the main reason that researchers use samples rather than populations?
It is difficult to develop eligibility criteria for populations.
Data from a sample are more accurate than data from a population.
It is more economical and efficient to work with samples.
Populations cannot be stratified and samples can.
The Correct Answer is C
A. Developing eligibility criteria for populations is not typically a reason for using samples instead of populations.
B. While data from a sample can sometimes be more manageable and easier to analyze, it's not accurate to say they are inherently more accurate than data from a population.
C. Working with samples is often more practical, economical, and efficient than attempting to gather data from an entire population, especially in large or geographically dispersed populations.
D. Populations can be stratified, but sampling allows researchers to select specific subgroups of interest from a population, making it easier to study specific characteristics or variables.

Correct Answer is A
Explanation
A. Reviewing the hospital's definition of workplace violence is important to ensure consistency with the findings of the study conducted elsewhere. This action will help the nurse manager understand how workplace violence is defined in their own hospital and whether changes need to be made based on the study's findings.
B. Developing a system for reporting workplace violence anonymously may be beneficial, but it is not directly supported by the findings of the study. It's important to first review the hospital's definition of workplace violence before implementing changes to reporting systems.
C. Repeating the study at the nurse manager's hospital may not be necessary and could be resource-intensive. Reviewing the existing literature and findings from other institutions can provide valuable insights without the need for replication.
D. Encouraging peer support among the nursing staff to report issues is a good practice, but it may not address the specific findings of the study regarding factors associated with reporting workplace violence.
