Context and sample integrity were considered when assigning confidence intervals.
These values range from low to high, but a recode of this variable also contains a description of their relative utility.
Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object.
It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.

Year: 1985 » Downloads & Basic Metadata The results of chronometric analysis on special specimen samples collected for dating can be found in this dataset.
Understanding the geologic history of an area and the different strata is important to interpreting and understanding archaeological findings.
The most commonly used chronometic method is radiocarbon analysis.
It measures the decay of radioactive carbon (14C) that has been absorbed from the atmosphere by a plant or animal prior to its death.
The development of Atomic Absorption Mass Spectrometry in recent years, a technique that allows one to count the individual atoms of 14C remaining in a sample instead of measuring the radioactive decay of the 14C, has considerably broadened the applicability of radiocarbon dating because it is now possible to date much smaller samples, as small as a grain of rice, for example.
Dendrochronology is another archaeological dating technique in which tree rings are used to date pieces of wood to the exact year in which they were cut down.
The most common relative dating method is stratigraphy.
