QuestionLeslie's poll may miss certain groups. Which is the best example of undercoverage? A) Some won't answer. B) Using a phonebook excludes unlisted and cell-only adults. C) Some may not participate.

Studdy Solution
Option C states that "Some adults who answer the phone may choose to not participate in the poll." This also does not represent undercoverage because it does not involve a segment of the population being inadequately represented in the sample. It's another matter of nonresponse, not undercoverage.
The best example of undercoverage is option B "If her campaign chooses numbers from the phonebook, they won't contact adults with unlisted numbers and adults who only use cell phones."
