Final answer:

To reduce the margin of error in polling, polling more people is necessary as it increases accuracy and representativeness.


Explanation:

The most effective way for the pollster to reduce the margin of error is to poll more people. By increasing the sample size, the poll will be more representative of the actual population, resulting in a lower margin of error.

A larger sample size makes a poll more accurate because it reduces the likelihood of unusual responses and improves representativeness of the population.

Increasing the number of respondents will enhance the poll's accuracy, providing a more precise picture of what people actually think or will do.
