Coins found in excavations may have their production date written on them, or there may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.

In historical geology, the primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young (radiocarbon dating with Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes.

Particular isotopes are suitable for different applications due to the type of atoms present in the mineral or other material and its approximate age.

Geologists also have radiometric methods for absolute dating based on radioactive decay of certain elements. So a low value of relative dispersion usually implies that the st. is small in comparison to the magnitude of the mean, as in a st. of 6cm for a mean of 4m would give a figure of 0.015 (1.5%) whereas with a mean of 40cm it would be 0.15 or 15%. However with measurements either side of zero and a mean close to zero the relative dispersion could be greater than 1.

Absolute dispersion usually refers to the standard deviation, a measure of variation from the mean, the units of st.

Absolute dating is a method of estimating the age of a rock sample in years via radiometric techniques.
