Repeatability Vs Reproducibility | Difference between Repeatability and Reproducibility

This page compares Repeatability vs Reproducibility and mentions difference between Repeatability and Reproducibility.

Repeatability

Definition: It describes closeness of output readings when the same input is applied repetitively over a short period of time. Following should be kept same during repetitive test/measurement.
• measurement conditions
• instrument
• observer
• location
• conditions of use

Reproducibility

Definition: It describes closeness of output readings for the same input when there are changes in the method of measurement, observer, measuring instrument, location, conditions of use and time of measurement.

• Both the terms repeatability and reproducibility describe the spread of output readings for the same input.
• The spread is known as repeatability if the measurement conditions are constant and known as reproducibility if the measurement conditions vary.
