Property value derived from a collection of results.
Notes:
- The term "consensus value" is typically used to describe estimates of a measure of location, such as mean value, median or mode, and dispersion derived from results reported by participants in a proficiency testing round (see participant in an interlaboratory comparison), but may also be used to refer to values derived from results of a specified subset of such results or, for example, from a number of laboratories chosen for their expertise for the particular analysis. See performance score and standard deviation for proficiency assessment.
- The consensus property value, when it is a value of a unitary quantity, may be expressed as a mean, median, or mode, and is then termed "consensus mean", "consensus median", or "consensus mode", respectively. The mode and the median also apply for ordinal quantities and the mode applies for nominal properties.
- A consensus property value is an example of assigned value.
- A consensus property value could, through appropriate actions, become a certified property value; this is in analogy to the certification of a reference material.
- A consensus property value may be obtained in a material-certification study or by agreement between appropriate organizations or experts.
