Observatio
Observatio est informationis acquisitio a fontibus primariis, quae in organismis vivis sensus occupatos tenet. Observatio in scientia sane datorum et perceptio quoque et collectio, instrumentorum scientificorum ope, significare potest. Observationes ad valores et quantitates et qualitates valere queant.

Observationes interdum erroris impetum sustinere possunt, ut docet effectus Hawthorne, secundum quem homines, si se observatos esse sentiunt, mores suos mutant.
