A set of codes that defines how a set of values are summarized in an aggregated computation, for use with sets of values do describe which aggregated statistic functions are to be applied (e.g., average, mode, min, max, standard deviation, variance).

Level	Code	System	Display	Definition
1	_ObservationMethodAggregate	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	observation method aggregate	Provides additional detail about the aggregation methods used to compute the aggregated values for an observation. This is an abstract code.
2	AVERAGE	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	average	Average of non-null values in the referenced set of values
2	COUNT	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	count	Count of non-null values in the referenced set of values
2	MAX	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	maxima	Largest of all non-null values in the referenced set of values.
2	MEDIAN	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	median	The median of all non-null values in the referenced set of values.
2	MIN	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	minima	Smallest of all non-null values in the referenced set of values.
2	MODE	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	mode	The most common value of all non-null values in the referenced set of values.
2	STDEV.P	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	population standard deviation	Standard Deviation of the values in the referenced set of values, computed over the population.
2	STDEV.S	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	sample standard deviation	Standard Deviation of the values in the referenced set of values, computed over a sample of the population.
2	SUM	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	sum	Sum of non-null values in the referenced set of values
2	VARIANCE.P	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	population variance	Variance of the values in the referenced set of values, computed over the population.
2	VARIANCE.S	http://terminology.hl7.org/CodeSystem/v3-ObservationMethod	sample variance	Variance of the values in the referenced set of values, computed over a sample of the population.

Explanation of the columns that may appear on this page:

Level

A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies

System

The source of the definition of the code (when the value set draws in codes defined elsewhere)

Code

The code (used as the code in the resource instance)

Display

The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application

Definition

An explanation of the meaning of the concept

Comments

Additional notes about how to use the code
