Final answer:
Asking to confirm accuracy is a query which is an essential aspect of scientific research for validation and reliability of findings. It allows precision and accuracy to be evaluated and ensures unbiased results. Therefore, the correct option is C.a query.
Step-by-step explanation:
Asking to confirm accuracy of an answer is considered a query. This is commonly used in scientific methods to ensure that the results are both reliable and can be replicated. It allows for a thorough understanding and verification of findings. To exemplify with the given context:
- Set a is precise, but inaccurate: The measurements are clustered closely together but do not align with the correct value.
- Set c is both precise and accurate: The measurements are not only close to each other but also to the true value.
- Set d is neither precise nor accurate: The measurements are scattered and do not align with the correct value, indicating both lack of precision and accuracy.
Research that lacks a why question or has wording that suggests a specific answer may not provide deep insights or unbiased results. For instance, in scientific poll design, a leading question can lead to biased outcomes and isn't an effective element of the design.
