SAINMHÍNIÚ the absolute value of the coefficient of variation ( IATE:1594321 ) TAGAIRT Wikipedia http://en.wikipedia.org/wiki/Relative_standard_deviation [8.12.2009]
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.
