Detailed Solution
Download Solution PDFThe correct answer is: 2) The closeness of a measured value to the true value
Explanation:
Accuracy in measurement refers to how close a measured value is to the true or accepted reference value. It quantifies the absence of systematic errors (bias).
Key Properties of Accuracy:
- True Value Proximity: High accuracy means minimal deviation from the actual value.
- Independent of Precision: A measurement can be accurate but not precise (or vice versa).
Why Not the Other Options?
-
Variation due to environmental factors → Describes precision (repeatability) or sensitivity to disturbances, not accuracy.
-
Ability to repeat the same measurement → Defines precision, not accuracy.
-
Smallest detectable change → Refers to resolution, not accuracy.
