Range
|
|
When used to refer to a radiocarbon "date", range refers to the span of years contained within the 1 or 2 sigma (standard deviation) error. Radiocarbon age ranges should never be thought as a single point in time, rather as a probability (never 100%, unless the error range grows to useless proportions) that the sample died within a span of some number of years.
