Name

Name of the variable you currently have selected, for example: Q1

Lock Name

When set to Yes this stops the variable being renumbered

Label

This is a full description of the variable that will appear in the data entry and on all analysis reports. By default, this displays the editable variable grid label in grids and semantic scales or as the question text in other question styles.

Text

Displays the editable question text

Response

Response types shown will depend on the question style selected. The response will determine the number of replies that are possible and the way in which they are recorded when data entry is completed. Single: allow only one answer to be selected Multiple: allow more than one answer Quantity: accept numerical answers Date: accept suitable date formats, e.g., dd/mm/yy Time: accept suitable time formats, e.g., 2.30pm Literal: allow any text

Must answer

Yes forces this question to be asked during data entry. No allows the question to be kept blank

Not asked

Not Asked conditions are set to assist with the routing in a questionnaire and with survey analysis, by excluding certain categories of respondents

Initial value

A default value that will be displayed during the interview or data entry. If read only is set then this can be an expression defining a calculated value.

Read only

When set to Yes, prevents the respondents from setting the answer

Aria role

Assign a custom role to the question in the published output to improve accessibility

Properties for closed questions only

Property

Description

Code count

The number of codes in the variable.

Ordering

Select the ordering method to use when rotating codes or grid as data is being entered. Only applies to questions with a fixed list of responses.

Inverse: question codes alternate between each case in normal and reverse order

Forward: codes appear in the same order but always start forward one

Random: codes appear in a random order

Alphabetic: codes appear in alphabetical order

Ordering exclude

Specify the codes that are excluded from ordering. When ordering, the selected codes will always be moved to the end of the list.

Ordinal

An ordinal question is a single response question where the answer codes form a sequence. Set to Yes to preserve the order of the question.

Mask

Specifies which codes are visible according to previous responses.

Auto answer

Automatically answer a masked multi-choice question: if only one response is possible, or if the number of responses available is less than the value set for Min.
