incorrect answer(s)

Explanation:

Analyze scientific polling criteria

To accurately measure public opinion and forecast an election, pollsters must design a scientific poll. Key requirements include:

1. Ability to randomly select respondents: Essential for a representative sample where every individual has an equal chance of selection.
2. A large sample: Necessary to reduce the margin of error and increase statistical reliability.
3. Wording of survey questions: Questions must be neutral and clear to avoid leading or biasing the respondents.

Evaluate social desirability bias

Ensuring that respondents make socially desirable answers is a source of polling bias (social desirability bias), which distorts true public opinion. Pollsters try to minimize or control for this bias, rather than "ensuring" it happens.
