measurement of a single variable or single value derived logically and/or algebraically from other measured or derived values An Act of recognizing and noting information about Note: the subject, and whose immediate and primary outcome (post-condition) is new data about a subject. Observations often involve measurement or other elaborate methods of investigation, but may also be simply assertive statements. Discussion: Structurally, many observations are where the Observation.code (inherited from Act) is the name and the Observation.value is the value of the property. Such a construct is also known as a (a named feature that can assume a value); “variable” hence, the Observation class is always used to hold generic name-value-pairs or variables, even though the variable valuation may not be the result of an elaborate observation method. It may be a simple answer to a question or it may be an assertion or setting of a parameter. As with all Act statements, Observation statements describe what was done, and in the case of Observations, this includes a description of what was actually observed (“results” or and those or are part of the “answers”); “results” “answers” observation and not split off into other objects.
