Public Opinion, Polls, News & Digital Information — Drills · Grade 12 Social Studies

Chapter: Civic Participation & Public Policy

What these drills covers

By the end of Public Opinion, Polls, News & Digital Information you should be able to:

4 questions, written answer, each with a worked explanation.

Vocabulary used: population, sample, nonresponse, sampling uncertainty, framing.

Problem 1

Why does a high support percentage among respondents not necessarily describe the population?
Answer and explanation

Selection and nonresponse may affect who answered. The percentage measures the supplied respondents under the question and method. Population inference needs evidence that the method supports that generalization, not just a large-looking share.

Problem 2

Why does a sampling margin not remove every possible poll error?
Answer and explanation

It concerns sampling uncertainty under specified assumptions. Coverage, nonresponse, wording, timing, and measurement can introduce other problems. Evaluate the complete method rather than treating one margin as a guarantee of total accuracy.

Problem 3

What should be checked when a headline expands a study’s conclusion?
Answer and explanation

Compare the original study’s population, period, method, outcome, and limitation with the headline. A bounded finding does not establish universal success. Identify the specific expansion instead of dismissing all research or accepting the headline automatically.

Problem 4

Why should a correction identify what remains supported?
Answer and explanation

It prevents an error from becoming either total dismissal or continued exaggeration. State the corrected measure and scope, retain valid evidence, and explain which broader inference no longer follows.
