Public Opinion, Polls, News & Digital Information — Drills · Grade 12 Social Studies
Chapter: Civic Participation & Public PolicyWhat these drills covers
By the end of Public Opinion, Polls, News & Digital Information you should be able to:
- I can identify population, sample, and response.
- I can explain a civic or economic mechanism using evidence, assumptions, and a qualified conclusion.
4 questions, written answer, each with a worked explanation.
Vocabulary used: population, sample, nonresponse, sampling uncertainty, framing.
Problem 1
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
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
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
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.
