gaussian distribution
usually the reference range for analytes is based on normal distribution (95% CV)
all values are symmetrically distributed around the mean
standard deviation
statistic that describes the variance or spread of a set of measurements about the mean
larger the ____, the greater the variance
% coefficient of variation
standard deviation / mean
expressed as %
measure of variability
aim to have this LOW for lab tests
