This code system http://hl7.org/fhir/CodeSystem/measure-aggregate-method defines the following codes:

Code | Display | Definition
sum | Sum | The measure score is determined by adding together the observations derived from the measure population.
average | Average | The measure score is determined by taking the average of the observations derived from the measure population.
median | Median | The measure score is determined by taking the median of the observations derived from the measure population.
minimum | Minimum | The measure score is determined by taking the minimum of the observations derived from the measure population.
maximum | Maximum | The measure score is determined by taking the maximum of the observations derived from the measure population.
count | Count | The measure score is determined as the number of observations derived from the measure population.
