Title: StatisticalVariable - Schema.org Type
Description: Schema.org Type: StatisticalVariable - StatisticalVariable represents any type of statistical metric that can be measured at a place and time. The usage pattern for StatisticalVariable is typically expressed using Observation with an explicit populationType, which is a type, typically drawn from Schema.org. Each StatisticalVariable is marked as a ConstraintNode, meaning that some properties (those listed using constraintProperty) serve in this setting solely to define the statistical variable rather than literally describe a specific person, place or thing. For example, a StatisticalVariable MedianHeightPerson_Female representing the median height of women, could be written as follows: the population type is Person; the measuredProperty height; the statType median; the gender Female. It is important to note that there are many kinds of scientific quantitative observation which are not fully, perfectly or unambiguously described following this pattern, or with solely Schema.org terminology. The approach taken here is designed to allow partial, incremental or minimal description of StatisticalVariables, and the use of detailed sets of entity and property IDs from external repositories. The measurementMethod, unitCode and unitText properties can also be used to clarify the specific nature and notation of an observed measurement.

In that case the subproperty of [[variableMeasured]] called [[measuredProperty]] is applicable.\n \nThe [[measurementTechnique]] property helps when extra clarification is needed about how a [[measuredProperty]] was measured. This is oriented towards scientific and scholarly dataset publication but may have broader applicability; it is not intended as a full representation of measurement, but can often serve as a high level summary for dataset discovery. \n\nFor example, if [[variableMeasured]] is: molecule concentration, [[measurementTechnique]] could be: \"mass spectrometry\" or \"nmr spectroscopy\" or \"colorimetry\" or \"immunofluorescence\". If the [[variableMeasured]] is \"depression rating\", the [[measurementTechnique]] could be \"Zung Scale\" or \"HAM-D\" or \"Beck Depression Inventory\". \n\nIf there are several [[variableMeasured]] properties recorded for some given data object, use a [[PropertyValue]] for each [[variableMeasured]] and attach the corresponding [[measurementTechnique]].
