Question

what is the degree of exactness of a measurement called?
○ error level
○ accuracy
○ degree of control
○ precision

Explanation:

To solve this, we analyze each option:

• "error level" refers to the amount of error, not exactness of measurement.
• "accuracy" is how close a measurement is to the true value, not the degree of exactness in the measurement process itself.
• "degree of control" is unrelated to measurement exactness.
• "precision" is defined as the degree of exactness (or reproducibility) of a measurement.

Answer:

D. precision
