Code Display Definition
average Average The [mean](https://en.wikipedia.org/wiki/Arithmetic_mean) of N measurements over the stated period
maximum Maximum The [maximum](https://en.wikipedia.org/wiki/Maximal_element) value of N measurements over the stated period
minimum Minimum The [minimum](https://en.wikipedia.org/wiki/Minimal_element) value of N measurements over the stated period
count Count The [number] of valid measurements over the stated period that contributed to the other statistical outputs
totalcount Total Count The total [number] of valid measurements over the stated period, including observations that were ignored because they did not contain valid result values
median Median The [median](https://en.wikipedia.org/wiki/Median) of N measurements over the stated period
std-dev standard deviation The [standard deviation](https://en.wikipedia.org/wiki/Standard_deviation) of N measurements over the stated period
sum sum The [sum](https://en.wikipedia.org/wiki/Summation) of N measurements over the stated period
variance variance The [variance](https://en.wikipedia.org/wiki/Variance) of N measurements over the stated period
%20 20th percentile The 20th [Percentile](https://en.wikipedia.org/wiki/Percentile) of N measurements over the stated period
%80 80th percentile The 80th [Percentile](https://en.wikipedia.org/wiki/Percentile) of N measurements over the stated period
4-lower lower quartile The lower [Quartile](https://en.wikipedia.org/wiki/Quartile) Boundary of N measurements over the stated period
4-upper upper quartile The upper [Quartile](https://en.wikipedia.org/wiki/Quartile) Boundary of N measurements over the stated period
4-dev quartile deviation The difference between the upper and lower [Quartiles](https://en.wikipedia.org/wiki/Quartile) is called the Interquartile range. (IQR = Q3-Q1) Quartile deviation or Semi-interquartile range is one-half the difference between the first and the third quartiles.
5-1 1st quintile The lowest of four values that divide the N measurementsinto a frequency distribution of five classes with each containing one fifth of the total population
5-2 2nd quintile The second of four values that divide the N measurementsinto a frequency distribution of five classes with each containing one fifth of the total population
5-3 3rd quintile The third of four values that divide the N measurementsinto a frequency distribution of five classes with each containing one fifth of the total population
5-4 4th quintile The fourth of four values that divide the N measurementsinto a frequency distribution of five classes with each containing one fifth of the total 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
Source 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
