Question

what does it mean if data are reproducible but not accurate?
the data can be produced over and over but are not close to the accepted value.
the data are close to the accepted value but cannot be produced over and over.
the data are close to the accepted value and are close to one another.
the data are close to the accepted value but are not close to one another.

Explanation:

To solve this, we analyze the definitions of reproducible (ability to get the same result repeatedly) and accurate (closeness to the accepted value).

• Option 1: "The data can be produced over and over (reproducible) but are not close to the accepted value (not accurate)" matches the description.
• Option 2: Describes data that is accurate (close to accepted) but not reproducible, which is the opposite.
• Option 3: Describes data that is both accurate and precise (close to each other), not what we need.
• Option 4: Describes data that is accurate but not precise, which is not the case here.

Answer:

A. The data can be produced over and over but are not close to the accepted value.
