Kurzbeschreibung

This question type allows you to present your survey participants a list of possible answers/options, which they may then rank according to their preferences.


Ranking example.jpg


Example: Question_type_example_multiple_numerical_input.zip.

General options

Mandatory

Description

This option allows the survey administrators to request their respondents to answer to certain survey questions. If the mandatory questions are not answered, the respondents will not be able to proceed further. If you have a question with multiple subquestions and you require only certain subquestions to be answered, use the minimum answer attribute located under the Logic tab.

Available options

  • On
  • Off (default)


Relevance equation

Beschreibung

If the value of the relevance equation is "1" or "true", the question is "relevant" in the survey context, i.e. it is shown to the survey participant. If not, the question is hidden. Any survey question allows you to specify a relevance equation. This function is the successor of conditions and supports much more complex conditional logic.

Syntax-Hervorhebung

Whenever you save the relevance equation, it is evaluated and syntax-highlighted. Any errors will be color coded so that you can quickly detect and fix them.

Notice.png
Hint: To check if all the relevance equations are used correctly within your survey, read about our show logic file feature.


Gültige Werte

  • Any equation that makes use of the Expression Manager syntax, without surrounding curly braces.

Beispiele

Here are good examples of syntax highlighting.


Display

Question theme (question_theme)

Description

It allows you to use customized themes for the respective question.

Available options

  • Your created question themes which are located under the Question themes in the Themes panel.
Help.png Note: This feature is under development at the moment.


Hide tip (hide_tip)

Beschreibung

Most questions will usually include a tip that says "Please choose one of the following options" or a hint text on how to fill out the question. This attribute allows you to turn off or on this tips/hints.

These tips/hints include validation criteria messages (such as min/max number of answers, min/max/equals sum value). If hide_tip is enabled, these messages will be hidden. However, if the user enters invalid data, the tips will appear. They will be coloured in red, getting changed to green once the validation criteria are met.

Available options

  • On - the tips/hints are hidden;
  • Off (default).



Random answer order (random_order)

Important.png
Attention : The order of randomization is currently not stored. So if the user is given the option to save/resume later the order will randomly change on resume.

Beschreibung

This attribute causes LimeSurvey to ignore the existing order of answer options/subquestions, and instead it orders them randomly. It is important to note that this random order will be reordered each time the question is displayed. So, if someone returns to a question, the order will probably be different from the first time she saw it. This option permits the survey creator to diminish the survey bias. Please note that if a question has subquestions, the order of subquestions will be randomized, not the order of the answer options.

Available options

  • Yes - Randomize on each page load
  • No (default)


Always hide this question (hidden)

Beschreibung

If enabled, the question will always be hidden - it will not be displayed to the survey participants. This function can be used in the following scenarios:

  • If you wish to prefill a question with a URL and you want not to have it displayed on the screen. This overrides any conditions used within the survey because the respective question will not even be embedded on the page.
  • If you wish to store or calculate a value on the fly via the Expression Manager.
Help.png Note: A common question type that is used with this function is the Equation one.

Available options

  • On
  • Off (default)


CSS class (css_class)

Description

If you want to add special CSS classes to certain questions, you can enter the CSS class name(s) in this box. Make sure you leave an empty space between different class names.

Valid values

  • Any text string with a space between different CSS class names.
Notice.png
Hint: You can also insert an expression in this box (New in 3.0.0 ). Remember that the output of the expression will not be updated dynamically.


Important.png
According to the W3C, CSS class names can contain only the characters [a-zA-Z, and 0-9] and ISO 10646 characters U+00A1 and higher, plus the hyphen (-) and the underscore (_). They cannot start with a digit, or a hyphen followed by a digit. LimeSurvey encodes CSS classes, but it does not fix it totally.


Show javascript alert (showpopups)

Description

Show an alert if answers exceeds the number of max answers. Else just update the expression manager tip (show it in red).

Available options

  • On (default option)
  • Off


Same choice height (samechoiceheight)

Description

If this option is enabled, then all the answer options defined within this question type will have the same height. For example, the height of the answer options usually defer from each other if they contain images (unless the dimension is the same across all your answer options).

Available options

  • On (default value)
  • Off



Same list height (samelistheight)

Description

The ranking question type makes use of a choice list (where all the answer options are displayed) and of rank list (where the answer options are ranked). If this option is activated, both lists will have the same height.

Available options

  • On (default value)
  • Off



Relevance help for printable survey (printable_survey_relevance_help)

Description

If you wish to print a survey, you can also print the relevance equations for each question. But, if you wish to offer instead an explanation rather than the expression on the printed form, fill in this box with the text explanation for the relevance equation.

Valid values

  • Any text and/or numbers you wish to be displayed on the printable form.


Logic

Minimum answers (min_answers)

Beschreibung

This function can be used to ensure that a user selects at least a certain number of answers in a multiple choice question.

Valid values

  • Any integer value above 0
  • Any number
  • Any SGQA code
  • Any question code (variable name)
  • Any equation, using Expression Manager syntax, without surrounding curly braces.

Beispiel

If set to X (a random number), the users can submit the survey form if they select at least X checkboxes. If this option is utilised for ranking questions, this ensures that at least three items are ranked before allowing the respondent to submit the answers/survey.

Help.png Please note that if you use this attribute with Ranking questions, you have to set the question to non-mandatory. Otherwise, all the items need to be ranked which is counter-intuitive if you decide to use the min_answers function too.



Maximale Antworten (max_answers)

Beschreibung

It can be used to limit the total number of answers a user can select in a multiple choice question.

Valid values

  • Any number value
  • Any SGQA code
  • Any question code (variable name)
  • Any equation, using Expression Manager syntax, without surrounding curly braces.

Beispiel

If set to 2, the user will only be able to check at most two checkboxes or one checkbox + fill the "Other" field (if any). For the Ranking question type, the participant would be able to select maximum two items.


Maximum columns for answers (max_col_for_ans)

Description

This option limits the number of columns created in the database (more precisely, in the answers table). If you give a value lower than maximum answers option, then this attribute will represent the upper limit of the maximum choices a respondent can make.

Valid Values

  • Any positive numerical value
  • The default value is the total number of answer options your question contains. The number will be displayed after you activate for the first time the survey.



Matrix Filter (array_filter)

Beschreibung

The Array filter setting allows you to use any multiple choice question to select or set which responses are displayed in a subsequent list, array or multiple choice question.

The subsequent questions can be filtered on any array question type, including:
  • Multiple choice
  • Multiple choice with comments
  • Multiple short text
  • Multiple numeric
  • Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, Column)
  • Array (Dual Scale, Text, Numbers)
  • Ranking

Furthermore, each of these question types can be filtered.

The only exception is Array (Column), which can filter other questions, but not itself.

How to set a filter

To set a filter, enter the question code of a multiple options question in the array filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array Filter' box to start the filtering process of the answers. Only the answer options that are selected in question Q1 will be visible in the array_filter-ed question.

If you wish more questions to be filtered via this option, type the question codes in the box separated by semicolons (;).
Important.png
The subquestion codes used in the first question must coincide with the subquestion codes from the second one. Otherwise, the array filter function will not filter the answers to the first question. Check the below example to better understand how the whole system works.

Kaskadierung

The selected options can be displayed in cascade. This means that you can select a question which filters another question, which filters another question, and so on.

Matrix Filter Beispiel

Let's take a look at the following example to better understand the power of this setting:


Array filter with multipe short text.jpg


In the screenshot from above, we got two questions. The first one is a multiple short text question type, while the second one is an array dual scale question type. The answers you provide in the first question will be listed in the second one. Technically, the answers you provide to the subquestions from the first question are filtered and displayed in the second question.

This example can be downloaded from the following link: limesurvey_group_32.lsg. Import this question group into your LimeSurvey installation.



Array exclusion filter (array_filter_exclude)

Beschreibung

The Array filter exclusion setting allows you to use any multiple choice question to select or set which responses are NOT displayed in a subsequent list, array or multiple choice question.

The subsequent questions can be filtered on any array question type, including:
  • Multiple choice
  • Multiple choice with comments
  • Multiple short text
  • Multiple numeric
  • Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, By column)
  • Array (Dual Scale, Text, Numbers)
  • Ranking

Außerdem kann jeder dieser Fragetypen an sich gefiltert werden.

The only exception is Array by column which can filter other questions, but it cannot be filtered.

How to set it up

Enter the question code of a multiple options question in the array exclusion filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the non-selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array exclusion filter' box to start the filtering process of the answers. Only the answer options that are NOT selected in question Q1 will be visible in your question.

If you wish more questions to be filtered via this option, type the question codes in the box separated by semicolons (;).
Important.png
The subquestion codes used in the first question must coincide with the subquestion codes from the second one. Otherwise, the array exclusion filter function will not filter the answers to the first question. Check the below example to better understand how the whole system works.

Cascading

The selected options can be displayed in cascade. This means that you can select a question which filters another question, which filters another question, and so on.

Beispiel

Let's see together the below example:


Example array filter exclude.png


In the screenshot from above, we got two questions. The first one is a multiple choice question type, while the second one is a multiple choice with comments question type. The answers you provide in the first question will be excluded from the second one. For example, if you select the ComfortUpdate option (that has the subquestion code 'SQ1') and the Plugin option ('SQ4'), the 'SQ1' and the 'SQ4' subquestion correspondents from the second question will be excluded. In our screenshot, we can observe that only the unselected options in the first question and displayed in the second one.

This example can be downloaded from the following link: Limesurvey_group_array_filter_exclude.zip. Import this question group into your LimeSurvey installation.

Randomisierungsgruppenname (random_group)

Beschreibung

It places the questions into a specified randomization group, all questions included in the specified group being displayed in a random order to the survey respondents.

Gültige Werte

Just enter any string you like (for example: 'group1'). All question which have set the same string within the randomization group name box will have their place in the survey randomized (=randomly exchanged among each other).



Question validation equation (em_validation_q)

Description

This is an equation that is used to validate the entire question (e.g, all of its parts collectively for a multi-answer question). If the question fails the validation criteria, then em_validation_q_tip message will be displayed (it uses the CSS style .error). This tip uses the .em_q_fn_validation CSS style, which is hidden by default within template.css.

The main difference between this feature and the subquestion validation equations (em_validation_sq option) is that for this feature, if the question (or question parts) fail validation, then an error message could be shown. For the subquestion validation, each text entry cell (e.g., in an array question type, but it can also be applied to single entry question types) will be styled so that the background color is (light) red.

Valid values

  • Any equation that makes use of the Expression Manager syntax, without surrounding curly braces.

Example

  • You want to collect demographic information from users via a multiple short text question, and you want to validate that the user has entered a valid email address and phone number.

This example shows how the question looks with invalid answers:

Validation-invalid-both.jpg

And here is what it looks like with one invalid answer:

Validation-invalid-phone.jpg

Here is how you edit a question to enter that information:

Validation-gui.jpg

And here is part of the Show Logic File output that lets you check the accuracy of your expression and ensure that there are no syntax errors:

Validation-logic.jpg

As you can see, the validation equation tests that both the email and phone number are either empty or match a regular expression filter.

The validation tip only shows the warning message if the phone or email appears invalid.

Notice.png
Hint: In order to create complex validation messages, read about the usage of the Expression Manager.


If you wish to import the example from above into your LimeSurvey installation, download the following .lsq file: Em_validation_q_example.zip.

Notice.png
Hint: Remember, LimeSuvey uses the Perl syntax for regular expressions, so they should start and end with / (slash character)!



Tip for whole question validation equation (em_validation_q_tip)

Description

If you are using the question validation equation, you can use this box in order to display an optional message as question tip on how the question has to be filled out.

Valid values

Example

See the example from the question validation equation wiki section- it shows how the tip can be tailored to show which parts of a multiple short text question fail the validation criteria.
