Which of the following is an advantage of using surveys for data collection in probability studies?

• A. Surveys can efficiently collect data from a large population, making it easier to estimate $probabilities$.
• B. Surveys guarantee that every response is completely accurate and truthful.
• C. Surveys always eliminate all forms of bias in data collection.
• D. Surveys are the only method that can be used to collect data for probability analysis.

Answer: (A)

Verified step by step guidance

1. Understand the purpose of surveys in probability studies: Surveys are tools used to gather data from a sample or population to estimate probabilities or understand characteristics.
2. Recognize that one key advantage of surveys is their ability to collect data from a large number of individuals efficiently, which helps in making reliable probability estimates.
3. Note that surveys do not guarantee that every response is accurate or truthful, as responses can be influenced by various factors such as misunderstanding or dishonesty.
4. Acknowledge that surveys cannot always eliminate all forms of bias, since biases can arise from question wording, sampling methods, or respondent behavior.
5. Remember that surveys are not the only method for collecting data in probability studies; other methods include experiments, observational studies, and existing data sources.
