Accuracy Vs Precision
Easychemistry
Repeated measurements close together but deviating from true value show:
Select the correct option:
Solution
Incorrect! Answer:
High precision and low accuracy
- Precision: Relates to the repeatability or consistency of the results. If multiple trials give values very close to each other (low standard deviation), the measurement set is highly precise.
- Accuracy: Relates to how close the average of the measurements is to the true or accepted value.
- Scenario: If a balance is calibrated incorrectly by +2g, every weighing will be consistent (precise) but will be incorrect relative to the truth (inaccurate).
- Conclusion: Clustered data far from the bullseye represents High Precision and Low Accuracy.
