ABSTRACT
A recently resolved debate centred on the interpretation of a major set of INAA data that was based on Olmec ceramics from Mexico. In an attempt to answer questions arising from the debate, this paper discusses the effect of numbers of samples chosen for data interpretation. It also presents interpretations of the ceramic data set based on a bivariate data-splitting approach and compares the results of this with the multivariate analysis approaches employed by the initial publishers of the data.
