Tipo de pregunta - Matriz en columnas
From LimeSurvey Manual
This question type is the same as an array, except the subquestion and answer axes are swapped.
Example: Array by column example.zip
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.
- On - Question must be answered before the participant can proceed to the next page - the answer option 'No answer' is never shown.
- Soft - If the question is not answered a warning is shown when trying to proceed to the next page - however the participant can choose to ignore the warning and proceeed. Note that the 'No answer' option is still shown (if activated in survey presentation settings)
- Off (default) - Question can be left unanswered
Condition (previously "Relevance equation")
If the result value of the condition 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.
Whenever you save the condition, it is evaluated and syntax-highlighted. Any errors will be color coded so that you can quickly detect and fix them.
- Any condition that makes use of the ExpressionScript syntax, without surrounding curly braces.
Here are good examples of syntax highlighting.
Answer width (answer_width)
This value sets the answer column width by using a percentage system. For example, if you type in this field 40, then 40 percent of the width of the question will be used for answers. The remaining width will be equally divided between the subquestions.
- Any integer value from 1 to 100.
Hide tip (hide_tip)
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.
- On - the tips/hints are hidden;
- Off (default).
Random answer order (random_order)
This attribute causes LimeSurvey to ignore the existing order of answer options/subquestions, and instead it orders them randomly. 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.
- Yes - Randomize when participant enters survey
- No (default)
Question theme (question_theme)
It allows you to use customized themes for the respective question.
- Your created question themes which are located under the Question themes in the Themes panel.
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 ExpressionScript - Presentation.
- Off (default)
CSS class (css_class)
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.
- Any text string with a space between different CSS class names.
Relevance help for printable survey (printable_survey_relevance_help)
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.
- Any text and/or numbers you wish to be displayed on the printable form.
Randomization group name (random_group)
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.
You can find a sample survey using randomization group name in ExpressionScript sample survey.
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).
Preview To preview the questions use the preview survey instead of the preview question group function, as the second has been reported to not show the questions in a randomized order.
Question validation equation (em_validation_q)
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.
- Any equation that makes use of the ExpressionScript syntax, without surrounding curly braces.
- 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:
And here is what it looks like with one invalid answer:
Here is how you edit a question to enter that information:
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:
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.
If you wish to import the example from above into your LimeSurvey installation, download the following .lsq file: Em_validation_q_example.zip.
Tip for whole question validation equation (em_validation_q_tip)
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.
- Any string or equation that makes use of the ExpressionScript syntax.
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.
Insert page break in printable view (page_break)
This attribute is only active when you actually print a survey from the Printable View. It forces a page break before the question.
- Off (default)
SPSS export scale type (scale_export)
- Default (default)
Show in public statistics (public_statistics)
This attribute allows the survey administrator to chose if a particular question results should be displayed to the survey participants after they submitted the survey.
The default setting for each question is 'Off' (=Do not show the question statistics to the respondents). You have to enable this for every single question if you want to show the survey statistics of that (those) particular question(s) to the survey participants after the survey submission.
- Off (default)
Display chart (display_chart)
This attribute allows the survey administrator to choose if a chart that contains the question results should be displayed to the survey participants after they filled out the survey.
- Off (default)
Chart type (chart_type)
This attribute allows the survey administrator to choose which type of chart will be displayed to the respondent once he/she finished filling out the survey.
- Bar chart
- Pie chart
