Loop with selection at each iteration

This type of variable presents a series of sub-questions that vary between interviews. The concept of selection at each iteration means that the loop will be treated as a closed question posed before each iteration. In the question list, loops with preliminary selection are indicated by the icon .

Example:

Variable type

Items

Washing powder

Loop with selection at each iteration

Number of iterations : 5

Which washing powder do you know ?

Ariel

Daz

Ecover

Fairy

Persil

Popularity

Closed question

Have you ever bought ??Washing powder?? ?

Yes

With this type of loop, at each iteration the respondent selects the next item on which the question (popularity, in our example) will be posed. The questionnaire will unfold as follows: popularity is asked only on the washing powders selected at each iteration of the loop.

Selection
Washing powder	Which washing powder do you know ?	Ecover
First iteration
Popularity	Have you ever bought Ecover ?	Yes
Selection
Washing powder	Which washing powder do you know ?	Persil
Second iteration
Popularity	Have you ever bought Persil ?	Yes
Selection
Washing powder	Which washing powder do you know ?	Don’t know
The respondent quits the loop washing powder, and moves on with the questionnaire.

The following properties are available to this variable:

Sub-variables visible during data-entry: Ensures that the variable and its sub-variables will be visible during data-entry. If un-ticked, the respondent will not see the variable, nor will he see and be asked the variable’s sub-variables.
Visible in Analyse: Ensures that the variable and its sub-variables will be visible in both AskiaAnalyse and AskiaVista. If un-ticked, the variable and its sub-variables will not appear in AskiaAnalyse and AskiaVista. Note: you can change this property even after a questionnaire's fieldwork is completed. Note that you can set this option for multiple questions at once by selecting the questions in the questionnaire list (in the left-hand pane), then right-clicking and selecting set questions, then visible in analyse in the context menu.
Develop level in Analyse: Enables you to access this variable’s data by levels in AskiaAnalyse.
Probability question in Analyse: Disposes of this variable’s data for probability analysis.
Number of iterations: Specifies the maximum number of iterations. By default, this property is set to the value of the global option default maximum number of responses.

The following properties are available to this variable’s items:

Rotation order: Enables you to assign a specific order to a variable’s items where Rotation has been activated. The following properties are available:
- Authorised: authorizes this item to be rotated.
- Fixed: ensures that this item will never be rotated.
- Always follow previous: ensures that this item follows right after its preceding item, regardless of the position the latter can be assigned as a result of a rotation.
Entry code: Specifies custom entry codes for this variable’s items. During data-entry, the Interviewer will therefore be able to select answer(s) from the list of items by typing the specified Entry codes. Note: You must specify entry codes to all the items of a variable. A variable’s entry codes must share the same character length. Furthermore, this option is restricted to questionnaires sent live in askiavoice.
Version: Enables you to assign the variable to one or all of the *.QES file’s versions. By default, a variable is assigned to all versions.
Link: enables you to re-use the item list from another variable in this variable. This option allows you to save time and reduces the likelihood of making errors when creating a questionnaire, and it also helps reduce the size of the *.QES file. For details, see linked items.
