Definition of Sample Size of Heavy Metals Concentration in Various Soils

摘要

This approach gives a useful preliminary information about a possibility of the parametrical description of an available data set and the sample size necessary for deriving of stable conclusions with the further statistical processing. Given statistical approach to the evaluation of the quantity and quality of data collection allows to plan the list of heavy metals and the quantity of samples which necessary to have in a future during a new field's researches.
