Therefore, it is recommended inspecting the scatterplot of the first two axes of correspondence analysis to find out if other factors play a role as well (see Examples 2 and 3).
He found that the graves he was uncovering contained no evidence of their dates and their discrete nature meant that a sequence could not be constructed through their stratigraphy. The assumption that design styles follow a bell curve of popularity – starting slowly, growing to a peak and then dying away as another style becomes popular – provides the basis for frequency seriation.
Petrie listed the contents of each grave on a strip of cardboard and swapped the papers around until he arrived at a sequence he was satisfied with. It also assumes that design popularity will be broadly similar from site to site within the same culture.
Seriation is a standard method of dating in archaeology.
It can be used to date stone tools, pottery fragments, and other artifacts.
In addition to temporal organization, seriation results may reflect assemblage differences in social status, age, sex or those resulting from regional variation (or a combination of two or more of these factors). 343) presents a seriation result of Danish hoards based on artefact types like daggers, axes, and swords.
