Which of the following is a blueprint used to ensure data collected represents a larger defined target population?

The correct choice refers to a sampling plan, which is indeed a blueprint used to outline how data will be collected to ensure that the sample accurately represents a larger defined target population. A sampling plan details the methodology, including the sampling technique, sample size, and the specific criteria for selecting participants from the population. This structured approach is vital in research to minimize bias and enhance the reliability of results, ultimately ensuring that findings can be generalized to the broader population.

A sampling unit, while also important, specifically refers to the individual elements or participants from whom data will be collected rather than the full outline of the data collection strategy. The sampling frame is a related concept that defines the actual list or database from which the sample is drawn but does not encompass the full planning process. Quota selection is a sampling technique that can be part of a sampling plan but does not represent the comprehensive strategy as a whole.
