Galen Druk:2022年美国中期选举民调的准确性达到了至少1998年以来的最高水平,平均误差仅为4.8个百分点,几乎没有党派偏见。这表明,尽管存在一些担忧,但民调的准确性仍然很高。 Nate Silver:虽然2022年的民调结果令人鼓舞,但长期来看,民调的准确性仍然存在一些挑战,例如回应率下降等问题。此外,公众对民调的看法也存在波动,有时过于乐观,有时过于悲观。 Nathaniel Rakich:FiveThirtyEight使用三种方法来衡量民调的准确性:平均误差、正确预测胜选结果的比例以及党派偏见。2022年的平均误差很低,但正确预测胜选结果的比例却是自1998年以来最低的。这可能是因为2022年的选举竞争非常激烈,以及民调机构的预算有限,导致对非竞争性选区的民调减少。此外,2022年的民调对民主党的偏见很小,与2020年和2016年相比有所改善。一些民调机构,特别是那些倾向于共和党的机构,在2022年的准确性较低,例如特拉法加集团。FiveThirtyEight对高产出民调机构进行权重调整,以避免其过度影响结果。整体而言,2022年众议院民调的准确性最高,这可能是因为使用了更多全国性的民调数据。 Galen Druk:2022年民调结果显示,尽管存在一些挑战,但民调的准确性仍然在历史标准范围内。
