The oldest rocks ... WebNov 29, 2024 · Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an “isochron”) by means of standard linear regression methods of statistics. The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.
