Tipologie di domande
From LimeSurvey Manual
Informazioni generali
In questa pagina verrà fatta una panoramica generale su tutte le tipologie di domande presenti in LimeSurvey, per poi passare ai dettagli di ciascuna tipologia.
Nel pacchetto di installazione di LimeSurvey è presente inoltre un esempio di indagine che contiene tutti i tipi di domande. L'esempio si trova nella cartella "/docs/demosurveys", è poi possibile importarlo e provarlo!
Sotto-domande
Il significato di sotto-domande è stato introdotto dalla versione di LimeSurvey 1.90 e successive. Tuttavia le sottodomande esistevano anche nelle versioni precedenti anche se denominate in modo diverso e spesso nascoste dalle Label sets. Con la versione 1.90 la loro definizione diventa più chiara e intuitiva.
Cosa sono le sottodomande
Solitamente ad una domanda corrisponde un gruppo di risposte, ma in alcuni casi (ad es. per le domande della tipologia "Array" o matrice) una domanda contiene al suo interno più sottodomande, alle quali l'intervistato dovrà rispondere (spesso utilizzando una lista predifinita di risposte o una scala di valori).
La tipologia di domanda più complessa è la "Scelta (testi)", in cui l'intervistato deve inserire una risposta per ciascuna combinazione della matrice visualizzata. In questi casi ciascun valore costituisce una risposta e la domanda sarà struttura con due liste di sotto-domande (la prima presente nelle righe e la seconda nelle colonne)
Formattazione delle domande
E' possibile creare un layout/formattazione generale di base per le domande utilizzando i files CSS. Per ulteriori informazioni consultare Stile di formattazione con CSS
Tipologie di domande
Arrays o Matrici
La tipologia "Array" (spesso definita come "Array flessibile") comprende diverse versioni che verranno esposte nel dettaglio in seguito. Grazie a questa tipologia, la domanda verrà visualizzata come una matrice in cui: -le righe corrispondono alle sottodomande -le colonne corrispondono alle risposte selezionabili. In questi casi la domanda potrà contenere un quesito specifico oppure guidare l'utente nella compilazione.
In termini di output (file con le risposte degli intervistati) verrà creata una variabile/colonna per ciascuna sottodomanda, alla stregua delle domande di tipo "Elenco (Pulsanti radio)".
Oltre alle tipologie più flessibili, come "Array","Array (numeri)" e "Scelta (testi)", LimeSurvey contiene una serie di matrici predefinite che semplicano la creazione dell'indagine.
Array
An array allows you to create a set of subquestions. Each of them uses the same set of answer options. For example, you can use this question type when you need feedback on several aspects of a particular product.

Scelta (punteggio 1-5)
It is an array type that is prefilled with answer choices. An 1 to 5 scale is used. A "No answer" answer option is automatically added if the question is not mandatory.
Hint: If you need scales other than 5 points, use the general array question type.

Scelta (punteggio 1-10)
It is an array question type that is prefilled with answer choices on a 1 to 10 scale. A "No answer" answer option is automatically added if the question is not mandatory.

Array (Numeri)
This question types allows survey administrators to a create large arrays with numbered dropdown boxes with a set of subquestions on the "y-axis", and another set of subquestions on the "x-axis".
You can also set a special question attribute to use this question type with checkboxes:
