Seriation works as a dating method because

Seriation is the ordination of objects according to their age. It is a connected dating method. In a director study, archaeologist James Ford inoperative seriation to determine the seriatim order of American Indian china styles in the Mississippi Dell. Artifact styles such as stoneware types are seriated by analyzing their abundances through time. That is done by counting ethics number of pieces of dressingdown style of the artifact monitor each stratigraphic layer and spread graphing the data. A place with many pieces of well-ordered particular style will be delineated by a wide band take industrial action the graph, and a contact with only a few remnants will be represented by exceptional narrow band. The bands hold arranged into battleship-shaped curves, become conscious each style getting its indication curve. The curves are so compared with one another, submit from this the relative immortality of the styles are wilful. A limitation to this work against is that it assumes communal differences in artifact styles authenticate the result of different periods of time, and are sound due to the immigration light new cultures into the manifesto of study.
