Answer: The poll that would yield the most scientifically accurate results is: O a poll of random households conducted door-to-door in major swing states
Step-by-step explanation:
A poll of random households conducted door-to-door in major swing states is likely to produce the most scientifically accurate results due to the use of random sampling. Random sampling ensures that each member of the population (in this case, households in major swing states) has an equal chance of being included in the survey. This method helps reduce bias and ensures that the sample represents the broader population, making the results more reliable and generalizable.
In comparison:
An exit poll conducted on Election Day in major swing states may be biased as it only captures the opinions of voters who have already cast their ballots, excluding those who haven't voted yet.
A poll of active voters conducted through surveys sent through the mail may have a response bias, as it relies on individuals voluntarily completing and returning the surveys, which may not accurately represent the entire population of active voters.
A telephone poll randomly conducted using landlines and cell phones around the country may also suffer from response bias, as it relies on individuals who are willing to respond to phone calls and may not capture those who do not have access to phones or prefer not to participate in telephone surveys.
Overall, the poll conducted door-to-door with random household sampling has the best chance of providing scientifically accurate results, as it aims to include a diverse and representative cross-section of the population being surveyed.
