Final answer:
A sampling frame is a designated group of people from whom a set of poll respondents is randomly selected.
Step-by-step explanation:
A random sample consists of a limited number of people from the overall population, selected in such a way that each has an equal chance of being chosen. The designated group of people from whom a set of poll respondents is randomly selected is called a sampling frame. It is important to have a sampling frame that accurately represents the population being studied as it affects the accuracy and generalizability of the survey results.
