An artifact is the error or misrepresentation introduced by a technique and/or technology. For example a poor pseudo-random number generator would introduce artifacts into statistical research models.

Artifacts of this kind include, but are not limited to:

• Artifact (medical imaging), misrepresentations of tissue structures seen in medical images
• Artifact (observational), any perceived distortion or other data error caused by the instrument of observation
• Compression artifact, data compression artifact in computer science, resulting from lossy data compression
• Digital artifact, a visible defect in a digital photo or video picture
• Sonic artifact, in sound and music production, sonic material that is accidental or unwanted, resulting from the editing of another sound
