Question type - Array (Numbers)/sl

Kratek opis

Ta tip vprašanja omogoča večjo tabelo podvprašanj na y osi, ter dodatni set podvprašanj na x osi, kjer se odgovor vpiše v polje, kjer se osi sečeta.

Pri tem tipu vprašanja lahko nastavite tudi odgovore v obliki potrditvenih polj (odgovor anketiranec obkljuka).

Splošen opis

The Array (Numbers) question type allows a large array of numbered dropdown boxes with a set of subquestions as the "y-axis", and another set of subquestions as the "x-axis". It provides for a very large display of question and answers. By default the dropdown box contains the numbers from 1 to 10, however this can be changed by adjusting the advanced question settings.

The behavior is like this:

• If you only specify a minimum value the range will adjust as min value + 10
• If you only specify a maximum value, the range will be 1 and maximum value.
• When both minimum and maximum value are present and if the minimum value is greater than the maximum value, no dropdown box will be displayed otherwise it works as usual.

Glavne nastavitve

Obvezno

Opis

Ta možnost skrbnikom ankete omogoča, da od svojih anketirancev zahtevajo, da odgovorijo na določena anketna vprašanja. Če na obvezna vprašanja ne odgovorijo, anketiranci ne bodo mogli nadaljevati. Če imate vprašanje z več podvprašanji in zahtevate odgovor le na določena podvprašanja, uporabite atribut minimalni odgovor, ki se nahaja pod zavihkom Logika.

Razpoložljive možnosti

• Vklopljeno - na vprašanje je treba odgovoriti, preden lahko udeleženec nadaljuje na naslednjo stran - možnost odgovora 'Brez odgovora' ni nikoli prikazana.
• Soft - Če na vprašanje ni odgovorjeno, se ob poskusu nadaljevanja prikaže opozorilo naslednja stran - vendar se lahko udeleženec odloči, da opozorilo prezre in nadaljuje. Upoštevajte, da je možnost 'Brez odgovora' še vedno prikazana (če je aktivirana v nastavitvah predstavitve ankete)
• Izklopljeno (privzeto) - Vprašanje lahko ostane brez odgovora

Preverjanje (z uporabo regularnih izrazov) (preg_validation)

Opis

Ta možnost vam omogoča, da določite regularni izraz, s katerim lahko potrdite vse dele vprašanja.

Če vrednost katerega koli vprašanja ali podvprašanja ne izpolnjuje zahtev za preverjanje veljavnosti, bo barva ozadja polja za vnos besedila spremenjena v rdečo, tako da lahko uporabniki zlahka vidijo, katere dele vprašanja je treba popraviti. Tako lahko opravite preverjanje na strani. Na ta način vam 'ne bo treba čakati, da uporabnik klikne na gumb za oddajo, da potrdi zadevno vprašanje.

'Veljavne vrednosti

• Vsak veljaven regularni izraz

Pogoj (prej "Enačba ustreznosti")

Opis

Če je rezultat pogoja »1« ali »true«, je vprašanje v kontekstu ankete »relevantno«, torej se prikaže anketirancu. Če ne, je vprašanje skrito. Vsako anketno vprašanje vam omogoča, da določite enačbo pomembnosti. Ta funkcija je naslednica pogojev in podpira veliko bolj zapleteno pogojno logiko.

Označevanje sintakse

Kadarkoli shranite pogoj, je ovrednoten in sintaktično poudarjen. Morebitne napake bodo označene z barvami, da jih boste lahko hitro odkrili in odpravili.

 Hint: Če želite preveriti, ali so vsi pogoji v vaši anketi pravilno uporabljeni, preberite o naši funkciji prikaži logično datoteko.

Veljavne vrednosti

• Kateri koli pogoj, ki uporablja sintakso ExpressionScript brez okoliških zavitih oklepajev.

Napredne nastavitve

Answer width (answer_width)

Description

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.

Valid values

• Any integer value from 1 to 100.

Maximum value (multiflexible_max)

Description

Multiflexible_max is available only in the Array (Numbers) question type.

This sets the maximum numeric value for the dropdown lists.

Valid values

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

Example

To set a dropdown box from 1 to 10, type in this box "10".

Minimum value (multiflexible_min)

Description

Multiflexible_min is available only in the Array (Numbers) question type.

This sets the minimum numeric value for the dropdown lists.

Valid values

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

Example

To set a dropdown box starting from 7, set this attribute to 7.

Step value (multiflexible_step)

Description

Only available in Array (Numbers) question type. Sets the numeric step value for the dropdown lists.

Example

To set a dropdown box starting at the number 2, and going to 10 in 2's (ie: 2, 4, 6, 8, 10); set this attribute to 2.

Checkbox layout (multiflexible_checkbox)

Description

The checkbox layout is available only within the Array (Numbers) question type. If enabled, the survey respondent will be able to answer the subquestions by ticking the right answer via checkboxes.

This attribute will automatically use multiflexible_min=0, multiflexible_max=1, and multiflexible_step=1, regardless the custom values entered in the respective boxes.

Available options

• On
• Off (default)

Example

If enabled, the array (numbers) question type will look like this:

Insert page break in printable view (page_break)

Description

This attribute is only active when you actually print a survey from the Printable View. It forces a page break before the question.

Available options

• On
• Off (default)

Show in public statistics (public_statistics)

Description

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.

Note: To have the statistics displayed on the last page, do not forget to enable this functionality from the presentation & navigation settings. Otherwise, no statistics link will be displayed at the end of your 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.

Available options

• On
• Off (default)

Random answer order (random_order)

Description

  As of 5.5.0, this attribute is not longer used for ordering answer options. Please see QS:Answer_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.

Available options

• Yes - Randomize when participant enters survey
• No (default)

SPSS export scale type (scale_export)

Description

This is used for SPSS export only. This attribute overrides the default scale guessed by SPSS. To learn what the different measurement scales do, please read the related SPSS documentation.

Available options

• Default (default)
• Nominal
• Ordinal
• Scale

Array filter (array_filter)

Description

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 (;).

  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. Note: When you want to filter the "other" answer option from the first question, you need to provide a subquestion for this answer in the second question and the subquestion code for this answer needs to be "other". Check the below example to better understand how the whole system works.

If multiple choice allow other setting: you can choose other for subquestion code and filter with other checked or not.

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.

Array filter example

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

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)

Description

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

Furthermore, each of these types of questions can filtered.

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 (;).

  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.

Example

Let's see together the below example:

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.

Minimum answers (min_answers)

Description

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 ExpressionScript syntax, without surrounding curly braces.

Example

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.

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.

Maximum answers (max_answers)

Description

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 ExpressionScript syntax, without surrounding curly braces.

Example

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.

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 ExpressionScript 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:

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.

 Hint: In order to create complex validation messages, read about the usage of the ExpressionScript.

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

 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

• Any string or equation that makes use of the ExpressionScript syntax.

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.

Sub-question validation equation (em_validation_sq)

Description

This is an equation that is used to validate each subquestion (text field) individually. Any text field that does not pass these validation conditions will have its background color turned pink (using the .em_sq_fn_validation CSS style) to highlight the error. Note that this is available in addition to the regular expression-based validation option.

Valid values

Any equation that makes use of the ExpressionScript syntax, without surrounding curly braces.

Examples

For example, if you want to allow only numbers that are a multiple of 3 as answers, the equation would be:

(this / 3) == floor(this/3)

The reserved variable this is automatically replaced by a reference to the active text entry cell.

Tip for sub-question validation equation (em_validation_sq_tip)

Description

If you are using em_validation_sq, this is an optional message/tip that will be displayed if the introduced answer is incorrect.

Valid values

• Any string

Example

• Continuing the example of validating emails, the tip might be "Please enter valid email addresses."
