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).

Expansion based on ObservationMethod v2.1.0 (CodeSystem)
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 |
