Question

If a public opinion survey reports finding that a particular candidate is supported by 60 percent of voters and that there is a 95 percent chance that support for this candidate is somewhere between 63.1 percent and 56.9 percent, the 3.1 percent variation from 60 percent is called:___________________.

Answer 1

Answer:

Margin of error

Explanation:

All surveys have margins of error because they consist of a limited sample out of a population that can be millions of times bigger. The less representative the sample, the higher the margin of error.

And a representative sample is one that surveys a considerable amount of people out of the population.

In this case, a 3.1 margin of error is very low, and for this reason alone, we can say that the survey is good, and the sample, representative.
