Extraordinary Claims Require Extraordinary Evidence

[RoadRunner79]

An example is an analogy, whereas an anecdote is opinion.

Or, to put it another way, I believe an example is an instance that demonstrates an established rule, whereas an anecdote is an instance that purports to establish a rule (or at least nudges in that direction).

So then, it would be a matter of prospective, and when used as the argument, an example would be an anecdote correct? I did look up the definitions, and some definitions do seem to blur the lines.
