SAINMHÍNIÚ measure of how close or how far data points are from their average, or deviates from the mean - which, in a data sample, is estimated as the positive square root of the sum of the squares of the deviations between the observations and the mean of the data, divided by one less than the total number of observations TAGAIRT COM-EN, based on: <BR>IUPAC. Compendium of Chemical Terminology, 2nd ed. (the "Gold Book"). Compiled by A. D. McNaught and A. Wilkinson. Blackwell Scientific Publications, Oxford (1997).

NÓTA The standard deviation is the positive square root of the <i>variance</i> [ IATE:1681483 ]. <BR>The variance and the closely-related standard deviation are measures of how spread out a distribution is. In other words, they are measures of variability.<BR>The variance is computed as the average squared deviation of each number from its mean.

NÓTA It is a measure of a statistical estimate's reliability obtained by dividing the standard error by the estimate; then multiplied by 100 to be expressed as a percent.<BR>In analytical chemistry is widely used for comparing the uncertainty between different measurements of varying absolute magnitude. It can be calculated with the formula: s<sub>r</sub> = s/x ̄<BR>

NÓTA It is recommended that the 'relative standard deviation' be reported, rather than the 'percentage standard deviation', in order to avoid confusion where results themselves are expressed as percentages. The term 'coefficient of variation' in place of 'relative standard deviation' is not recommended.
