Of course, these design styles are not eligible for chronological seriation.
For example, knives in early medieval times in Europe are said to show no chronological variation.
Initially 60 contexts (called units in Win Basp) were created along with 50 types.
Jørgensen 1992; Two different variants of seriation have been applied: contextual seriation and frequency seriation (Renfrew and Bahn 1996, pp. Whereas contextual seriation is based on the presence or absence of a design style, frequency seriation relies on measuring the proportional abundance or frequency of a design style.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.This is called the arch effect by Hill and Gauch (1980).Both Kendall and Jensen & Høilund Nielsen (1997) created artificial data sets to show that the parabola results in ideal circumstances.
