a measure of the accuracy of an opinion poll

Question

I need this answer for my government homework so I can study for an upcoming test.  Without this answer and more answers I won't be able to study.  

Answer 1

All valid opinion polls use statistical techniques to construct reliable questions and a statistically valid sample. The sample is constructed based upon a few questions asked at the beginning. An example of this would be, “Are you likely to vote in the upcoming election?”.

All polls have a “margin of error.” This in statistics called a “confidence level. That number, expressed as a percentage, is not randomly selected, but is a product of mathematical analysis in the construction the poll.

Good polls have a confidence level of 97%.

Another fact to consider in today’s world involves disinformation. Homeland Security and NSA analysts have publicly reported that a number of published polls in this election cycle were not valid, and they were in reality propaganda. The use of AI is also a factor in today’s world.

The final factor to consider in presidential elections is the the electoral college. Polls predict popular voting. Trump got around 51.5% of the popular vote. Harris got around 48.5%. This right at the +/- 3% margin of errors that major polls used. The polls were actually correct, just as they were in the 2016 elections.
