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.
