What's the difference between accuracy and fidelity?

Accuracy


Definition:

  • (n.) The state of being accurate; freedom from mistakes, this exemption arising from carefulness; exact conformity to truth, or to a rule or model; precision; exactness; nicety; correctness; as, the value of testimony depends on its accuracy.

Fidelity


Definition:

  • (n.) Faithfulness; adherence to right; careful and exact observance of duty, or discharge of obligations.
  • (n.) Adherence to a person or party to which one is bound; loyalty.
  • (n.) Adherence to the marriage contract.
  • (n.) Adherence to truth; veracity; honesty.

Example Sentences:

  • (1) These lysates are comparable to those of Escherichia coli in transcriptional and translational fidelity and efficiency in response to a given template DNA.
  • (2) Procaryotic DNA polymerases contain an associated 3'----5' exonuclease activity which provides a proofreading function and contributes substantially to replication fidelity.
