Properties¶
Name | Type | Cardinality |
---|---|---|
hasCategoryStatistic | CategoryStatistic | 0..n |
hasSummaryStatistic | SummaryStatistic | 0..n |
totalResponses | Integer | 0..1 |
hasCategoryStatistic¶
Statistics that provides a category specific values, filtered or unfiltered, weighted or unweighted, expressed as an xs:decimal or xs:double
hasSummaryStatistic¶
Statistic that provides a summary value, filtered or unfiltered, weighted or unweighted, expressed as an xs:decimal or xs:double

applicableWeightVariable¶
Reference to a variable to use for weight in calculating the statistic.
forInstanceVariable¶
Reference to the variable to which the statistics apply.
hasFilterVariable¶
A variable that may be used to filter the summary and/or category statistics (for example by country or by gender)
