The aggregate of those to whom a researcher wishes to generalize study results is which of the following?
A) Gatekeepers
B) Population
C) Sample
D) Sampling plan
B
Feedback:
A population is all the individuals or objects with common, defining characteristics (the "P" component in PICO questions). Gaining entrée to a research site for a particular population typically involves negotiations with gatekeepers who have the authority to permit entry into their world. Researchers typically collect data from a sample, which is a subset of the population. Using samples is more practical than collecting data from an entire population, but the risk is that the sample might not adequately reflect the population's traits. The researcher's sampling plan specifies how the sample will be selected and how many subjects there will be.
