Abstract
Statistics usually used in isotope geochemistry assume that values are normally distributed –repeat measurements are used to determine a mean and standard deviation; a standard error on the mean is then calculated from the standard deviation and the number of measurements in the distribution. However,the distribution of a ratio is asymmetric, and this leads to a systematic offset in the mean which can be larger than the calculated standard error.The systematic error depends on the standard deviation of the dataset from which the mean is calculated, and so depends on how measurements are binned to calculated ratios.
