On which two levels should one understand public opinion?

Question

Quizplus · Accepted Answer

Public opinion should be understood on both the aggregate level, which refers to the overall consensus of opinions held by a group of people, and the individual level, which refers to the attitudes and beliefs of individual members of that group. Understanding public opinion on both levels is important for accurately gauging the views and concerns of a given population. The other options - ideology and age, state and local, and race and gender - do not accurately reflect the two levels on which public opinion should be understood.
