Reproducibility - short version

(1) A desirable trait that occurs when different people can get the same measurement result at different times.

(2) The variation in measurements made by different people using the same measuring device to measure the same characteristic on the same product.

(3) Reproducibility refers to variation in a series of measurements that have been taken with one gage measuring one characteristic of the same item by different people.

Reproducibility - long version

Reproducibility is the ability of an experiment or study to be accurately reproduced, or replicated, by someone else working independently. It is one of the main principles of the scientific method.

The results of an experiment performed by a particular researcher or group of researchers are generally evaluated by other independent researchers who repeat the same experiment themselves, based on the original experimental description (see independent review). Then they see if their experiment gives similar results to those reported by the original group. The result values are said to be commensurate if they are obtained (in distinct experimental trials) according to the same reproducible experimental description and procedure.

Reproducibility is different from repeatability, which measures the success rate in successive experiments, possibly conducted by the same experimenters. Reproducibility relates to the agreement of test results with different operators, test apparatus, and laboratory locations. It is often reported as a standard deviation.
