Version: 5.0.0-ballot
Name: uncertainty
Title: null
Modifier: This extension is not a modifier extension
Status: draft
Definition: The primary measure of variance/uncertainty of the value (the square root of the sum of the squares of the differences between all data points and the mean).
Committee: FHIR Infrastructure Work Group

Status: draft. Extension maintained by: Health Level Seven International (Modeling and Methodology)

The primary measure of variance/uncertainty of the value (the square root of the sum of the squares of the differences between all data points and the mean).

Comment :

standardDeviation has the same units as the quantity. It is used to normalize the data for computing the distribution function. Applications that cannot deal with probability distributions can still get an idea about the confidence level by looking at standardDeviation.

Context of Use: Use on Element ID Quantity
