ABSTRACT
Part of the basis of the scientific method is that any experiment may be reproduced by another worker and/or another laboratory, provided the original protocol is rigidly adhered to. We have seen already that this is an ideal that the experimenter seeks to approach. However, a single worker - in a fixed spot, using the same apparatus or machine, the same batch of material, the same reagents - is faced with variability. Once we add the effects of geography, changed materials and equipment, and different operators, this variation is likely to be still greater. This global variation in the value of the response is known as the reproducibility.
