摘      要：Increasing volumes of of non-traditional stable isotope data have brought new opportunities to gain important insights into geochemical and planetary ***,there is a worrysome trend that the isotopic data are interpreted in a fashion that its statistical approaches are chosen *** communication summarizes the rules regarding calculating the mean,standard deviation and relative standard deviation of a population,as well as error propagation and significant *** rules should be used when reporting geochemical data,especially for isotope *** two examples,I show that statistics matters in isotopic data interpretation.
