What does sampling in research allow educators to do?

Sampling in research enables educators to gather information cost-effectively because it allows them to study a representative subset of a larger population rather than surveying or interviewing every individual within that population. By selecting a smaller, manageable group that reflects the diversity of the entire population, educators can draw meaningful conclusions and insights without the prohibitive time, effort, and resources required to reach out to everyone. This approach not only saves costs but also streamlines the data collection process while still maintaining the integrity and relevance of the findings.

In contrast, conducting interviews with all stakeholders would be impractical and expensive, while gathering data exclusively from teachers would limit the breadth of perspectives, and assuring complete accuracy of all data is often unattainable in research, as it is subject to various limitations and biases inherent in data collection methods.
