La reproducibilidad se refiere a la capacidad que tenga una prueba o experimento de ser reproducido o replicado por otros, en particular, por la comunidad científica. El término está estrechamente relacionado al concepto de testabilidad. Dependiendo del campo científico particular, la reproducibilidad puede requerir que la prueba o experimento sea falsable. La reproducibilidad es uno de los pilares del método científico. Los resultados de un experimento llevado a cabo por un investigador o grupo de investigación particular son evaluados generalmente por otros investigadores independientes reproduciendo el experimento original. Repiten el mismo experimento por sí mismos, basándose en la descripción del experimento original, y comprueban si su experimento tiene resultados similares a los comunicados por el grupo original. Se dice que los valores resultantes son conmensurables si se obtienen (en distintos procesos experimentales) de acuerdo con los mismos procedimientos experimentales descritos y reproducibles.

Reproducibility is the ability of an entire experiment or study to be duplicated, either by the same researcher or by someone else working independently. Reproducing an experiment is called replicating it. Reproducibility is one of the main principles of the scientific method. The values obtained from distinct experimental trials are said to be commensurate if they are obtained according to the same reproducible experimental description and procedure. The basic idea can be seen in Aristotle's dictum that there is no scientific knowledge of the individual, where the word used for individual in Greek had the connotation of the idiosyncratic, or wholly isolated occurrence. Thus all knowledge, all science, necessarily involves the formation of general concepts and the invocation of their corresponding symbols in language (cf. Turner). Aristotle′s conception about the knowledge of the individual being considered unscientific is due to lack of the field of statistics in his time, so he could not appeal to statistical averaging by the individual. A particular experimentally obtained value is said to be reproducible if there is a high degree of agreement between measurements or observations conducted on replicate specimens in different locations by different people—that is, if the experimental value is found to have a high precision.
