Question type - Equation/sl

Kratek opis

Opomba: Ta tip vprašanja je mogoč od verzije 1.92 dalje

Ta tip vprašanja dovoljuje avtorju, da izdela enačbo (npr.: izračun ali prilagojeno poročilo) ter jo shrani v podatkovno bazo kot spremenljivko. Za enačbo lahku uporabite sintakso, ki jo podpirac Urejevalnik izrazov. V primeru, da upravljate s številčnimi vrednostmi morate uporabiti napredne nastavitve "Samo števila", kot je opisano.

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

Condition (previously "Relevance equation")

Description

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.

Syntax Highlighting

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.

 Hint: To check if all conditions are used correctly within your survey, read about our show logic file feature.

Valid values

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

Examples

Here are good examples of syntax highlighting.

Advanced settings

Always hide this question (hidden)

Description

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.

Note: A common question type that is used with this function is the Equation one.

Available options

• On
• Off (default)

Note: unlike all other question types, if an equation is hidden, it is still computed and its value is still stored in the database.

Numbers only (numbers_only)

Description

If you enable this option, the participant can only enter numbers in the text box(es).

For the equation question types, this setting indicates that the result could only be a number, not a string. This will guarantee proper calculations/conversions in follow-up equations regarding the decimal mark.

Behavior by question type

1. Default: If the subject enters a value that is not a number, that value is immediately cleared from the text box so that the subject can enter an appropriate value.
2. Array (Texts): If the numbers only option is disabled, the "Show totals for" and "Show grand total" options will be overruled, while the total text boxes will not be displayed.
3. Equation: Enabling this option will force the equation results to be converted to a numeric value. If the equation result is not a number (and not blank), the equation will return NaN, being saved as an empty string in the response table.

Available options

• On
• Off (default)

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)

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
