Stone row variety is immense.
Stone rows vary considerably in form and character. Variety is perhaps their most consistent characteristic. There are four main types of row are single, double, triple and multiple. They vary in length between 3m and 3320m, are composed of between 3 and 922 stones which vary considerably in size even within some individual rows. When one also takes into account variations in the character of the surrounding broadly contemporary archaeology it is probably fair to conclude that each row is unique. In an attempt to quantify the degree of variation some of the row characteristics have been examined using statistical standard deviation techniques which is a means of quantifying the amount of variation within a set of data. Four different row characteristics have been examined and comparisons made between the regions. This allows us to establish which regions have the most diversity. Finally the results are combined to establish which regions have the most overall variability and which the least.
