Question

A Gallup poll conducted between April 20 and July 19, 2016, reported that 50.9 percent of Americans approved of President Obama. The survey consisted of 45,229 American adults. The Gallup poll has a margin of error of 1 percent. How can you interpret this poll?

Answer 1

Answer:

If we repeat the poll with the same techniques over and over again with the same 45,229 American adults, then the level of approval of President Obama could result in 51.9% or  49.9% considering a margin of error of 1 percent.

Explanation:

For the reason that a statistic poll is not unquestionable right, we have something called the Margin of error. It is a value that tells us about the confidence of a poll, survey, etc.

If we repeat the poll with the same techniques over and over again with the same 45,229 American adults, then the level of approval of President Obama could result in 51.9% or 49.9% considering a margin of error of 1 percent. Since we do not have data enough to show its confidence level numbers, we can say that most of the time, the result would match the 50.9% published by the Gallup.
