NumericDomainType

A response domain capturing a numeric response (the intent is to analyze the response as a number) for a question. Contains the equivalent content of a NumericRepresentation including the numeric range, numeric type code, format, scale, decimal position, and interval. Adds a set of elements available to all Response Domains; Label, Description, OutParameter, designation of response cardinality, and a declaration of an offset date for the data content. Has an equivalent NumericDomainReference which references a ManagedNumericRepresentation.

Properties

Name

Type

Description

Label

LabelType

0..n

A display label for the domain. Supports multiple language versions of the same content as well as optional formatting of the content. Repeat for labels with different content, for example, labels with differing length limitations.

Description

StructuredStringType

0..1

A description of the content and purpose of the domain. Supports multiple language versions of the same content as well as optional formatting of the content.

OutParameter

ParameterType

0..1

Allows for the response to be bound to one of the QuestionItem’s OutParameters, so the collected information can be used elsewhere, for example as inputs to subsequent questions in an Instrument or to a GenerationInstruction. If multiple responses are possible, this would represent and ordered array of the responses.

ResponseCardinality

ResponseCardinalityType

0..1

Allows the designation of the minimum and maximum number of responses allowed for this response domain.

ContentDateOffset

ContentDateOffsetType

0..1

Identifies the difference between the date applied to the data as a whole and this specific item such as previous year’s income or residence 5 years ago.

Description

NumberRange

NumberRangeType

0..n

Defines the valid number range or number values for the representation.

NumericTypeCode

CodeValueType

0..1

Identification of the numeric type such as integer, decimal, etc. supports the use of an external controlled vocabulary. The DDI Alliance has provided a controlled vocabulary (NumericType) to support this element at http://www.ddialliance.org/controlled-vocabularies.

Format

string

0..1

A format for number expressed as a string.

Scale

int

0..1

The scale of the number expressed as an integer (for example a number expressed in 100’s, 5 = 500 would have a scale of 100).

DecimalPositions

int

0..1

The number of decimal positions expressed as an integer (precision of the number).

Interval_IntervalType

nonNegativeInteger

0..1

The interval between valid responses expressed as an integer.

Accuracy

decimal

0..1

The level to which a number is considered to be accurate. Expressed as a decimal.

Description

RecommendedDataType

CodeValueType

0..1

This field provides the recommended treatment of the data within an application. The value should come from a controlled vocabulary - recommended values include the set found in W3C XML Schema Part 2, but excluding string sub-types, QNAME, and NOTATION. The DDI Alliance has provided a controlled vocabulary (DataType) to support this element at http://www.ddialliance.org/controlled-vocabularies.

GenericOutputFormat

CodeValueType

0..1

This field provides a recommended generic treatment of the data for display by an application. The value should come from a controlled vocabulary.

MeasurementUnit

CodeValueType

0..1

Records the measurement unit, for example, ‘km’, ‘miles’, etc. Supports the use of a controlled vocabulary.

MissingValue

string

0..1

List the values used to represent missing data in a space delimited array. Use of MissingValuesReference is preferred. If this content does not match the values provided in the MissingValuesReference, the content of the MissingValuesReference overrides the content of this attribute.

BlankIsMissingValue

boolean

0..1

When value is true a blank or empty variable content should be treated as a missing value. Use of MissingValuesReference is preferred.

ClassificationLevel

string

0..1

Indicates the type of relationship, nominal, ordinal, interval, ratio, or continuous. Use where appropriate for the representation type.
