This value set contains 21 concepts.
Code | System | Display | Definition |
average | http://terminology.hl7.org/CodeSystem/observation-statistics | Average | The mean of N measurements over the stated period. |
maximum | http://terminology.hl7.org/CodeSystem/observation-statistics | Maximum | The maximum value of N measurements over the stated period. |
minimum | http://terminology.hl7.org/CodeSystem/observation-statistics | Minimum | The minimum value of N measurements over the stated period. |
count | http://terminology.hl7.org/CodeSystem/observation-statistics | Count | The [number] of valid measurements over the stated period that contributed to the other statistical outputs. |
total-count | http://terminology.hl7.org/CodeSystem/observation-statistics | 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 | http://terminology.hl7.org/CodeSystem/observation-statistics | Median | The median of N measurements over the stated period. |
std-dev | http://terminology.hl7.org/CodeSystem/observation-statistics | Standard Deviation | The standard deviation of N measurements over the stated period. |
sum | http://terminology.hl7.org/CodeSystem/observation-statistics | Sum | The sum of N measurements over the stated period. |
variance | http://terminology.hl7.org/CodeSystem/observation-statistics | Variance | The variance of N measurements over the stated period. |
20-percent | http://terminology.hl7.org/CodeSystem/observation-statistics | 20th Percentile | The 20th Percentile of N measurements over the stated period. |
80-percent | http://terminology.hl7.org/CodeSystem/observation-statistics | 80th Percentile | The 80th Percentile of N measurements over the stated period. |
4-lower | http://terminology.hl7.org/CodeSystem/observation-statistics | Lower Quartile | The lower Quartile Boundary of N measurements over the stated period. |
4-upper | http://terminology.hl7.org/CodeSystem/observation-statistics | Upper Quartile | The upper Quartile Boundary of N measurements over the stated period. |
4-dev | http://terminology.hl7.org/CodeSystem/observation-statistics | Quartile Deviation | The difference between the upper and lower Quartiles 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 | http://terminology.hl7.org/CodeSystem/observation-statistics | 1st Quintile | The lowest of four values that divide the N measurements into a frequency distribution of five classes with each containing one fifth of the total population. |
5-2 | http://terminology.hl7.org/CodeSystem/observation-statistics | 2nd Quintile | The second of four values that divide the N measurements into a frequency distribution of five classes with each containing one fifth of the total population. |
5-3 | http://terminology.hl7.org/CodeSystem/observation-statistics | 3rd Quintile | The third of four values that divide the N measurements into a frequency distribution of five classes with each containing one fifth of the total population. |
5-4 | http://terminology.hl7.org/CodeSystem/observation-statistics | 4th Quintile | The fourth of four values that divide the N measurements into a frequency distribution of five classes with each containing one fifth of the total population. |
skew | http://terminology.hl7.org/CodeSystem/observation-statistics | Skew | Skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive or negative, or even undefined. Source: Wikipedia. |
kurtosis | http://terminology.hl7.org/CodeSystem/observation-statistics | Kurtosis | Kurtosis is a measure of the "tailedness" of the probability distribution of a real-valued random variable. Source: Wikipedia. |
regression | http://terminology.hl7.org/CodeSystem/observation-statistics | Regression | Linear regression is an approach for modeling two-dimensional sample points with one independent variable and one dependent variable (conventionally, the x and y coordinates in a Cartesian coordinate system) and finds a linear function (a non-vertical straight line) that, as accurately as possible, predicts the dependent variable values as a function of the independent variables. Source: Wikipedia This Statistic code will return both a gradient and an intercept value. |
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 |
