Understanding Survey Bias and Sampling

Chapter 12 covers conducting sample surveys and identifying different types of bias. It explains six types of bias, including undercoverage, non-response, convenience sampling, voluntary response, response bias, and leading questions. The chapter also outlines four effective sampling methods: simple random sampling, stratified random sampling, systematic sampling, and cluster sampling. The focus is on understanding vocabulary and recognizing bias in surveys, rather than mathematical computation.

What is the main focus of Chapter 12?

• Statistical analysis

• Mathematical computations

• Learning vocabulary and recognizing bias

• Conducting experiments

What is the difference between a census and a sample survey?

• Both a census and a sample survey sample part of the population.

• Both a census and a sample survey examine the entire population.

• A census examines the entire population, while a sample survey samples part of the population.

• A census samples part of the population, while a sample survey examines the entire population.

What is undercoverage bias?

• When the survey is conducted online.

• When a part of the population is underrepresented.

• When a part of the population is overrepresented.

• When the entire population is surveyed.

Which of the following is an example of non-response bias?

• Surveying only students in a cafeteria.

• Using a random number generator for sampling.

• People hanging up on phone surveys.

• Surveying everyone in a city.

In the student survey case study, what types of bias were present?

• Response and leading question

• None of the above

• Convenience and voluntary response

• Undercoverage and non-response

What is a major drawback of convenience sampling?

• It requires complex calculations.

• It is time-consuming.

• It is expensive.

• It does not effectively represent the population.

Voluntary response bias often occurs in which scenario?

• Mailing surveys to a random sample.

• Radio talk shows where listeners call in.

• Conducting surveys in person.

• Randomly selecting survey participants.

In the Domino's survey case study, which types of bias were identified?

• None of the above

• Only undercoverage and non-response

• Undercoverage, non-response, voluntary response, and convenience sampling

• Only voluntary response and convenience sampling

What is response bias?

• When a part of the population is underrepresented.

• When the entire population is surveyed.

• When the survey is conducted online.

• When respondents lie about their behaviors or attitudes.

What is a leading question?

• A question that is multiple-choice.

• A question that is open-ended.

• A question that persuades the respondent towards a point of view.

• A question that is neutral.
