The correct answer to fill in the blank is "error."

A margin of sampling error is a statistical calculation that provides insight into the accuracy of a poll's results. It indicates the degree to which the results of a survey may differ from the actual population values due to the sample selection. In polling, a smaller margin of error suggests that the results are more reliable, while a larger margin indicates a higher level of uncertainty. The margin of error is typically expressed as a percentage and is influenced by the size of the sample; larger samples generally yield smaller margins of error, reflecting greater precision in the results.
