## data point

Informatics
A “hard” measurable value that can be graphed or included in a database.

Vox populi
Like many real terms, popular use has morphed “data point” into a bullet point in a lantern-slide presentation, or “any anecdote or opinion disguised as fact that can be used to persuade others”.
