ABSTRACT/Full article not available/

An exploratory data analysis (EDA) technique is based on the box plot and
robust-class selection. Calculation of the threshold of anomalous data is based
on the determined classes. In contrast to classic statistical processing ( ), in these
methods, normalization isn’t needed. This paper is devoted to presentation of
EDA application on stream sediment survey data of 1:50000 Shirinkand sheet.
180 Samples were analyzed for 23 elements and because of high censored values
of Cd and P, they are omitted from data processing. Threshold and anomalous
values of collected data were determined by means of classic statistical methods
and EDA, that EDA results gain more reliability according to field checking.
