The value of the @[email protected], expressed in @[email protected] It can be calculated from the relative @[email protected] by multiplying by 100. Comment: It is recommended that the 'relative @[email protected]' be reported, rather than the 'percentage @[email protected]', in order to avoid confusion where results themselves are expressed as percentages. The term '@[email protected] of variation' in place of 'relative @[email protected]' is not recommended.
