From LimeSurvey Manual
Generale
Questa pagina fornisce una panoramica su tutti i tipi di domande disponibili, mentre in seguito verrà esposta nel dettaglio ciascuna tipologia.
Inoltre, il pacchetto di installazione di LimeSurvey contiene un'indagine esempio che contiene tutte le tipologie di domande. Cercalo in /docs/demosurveys-Directory - importalo e provalo!
Sottodomande
Breve spiegazione delle sottodomande
Solitamente ciascuna domanda possiede più risposte. Ci sono però alcuni tipi di domande (ad esempio le tipologie "Array" o matrici), che si compongono di molteplici sottodomande alle quali l'intervistato può rispondere scegliendo tra più opzioni, o più frequentemente, attribuendo un punteggio di valutazione su una scala predifinita.
La tipologia più complessa è "Array di testo" (matrice di testo) dove l'intervistato deve inserire un valore per ciascuna combinazione. In questo caso il valore inserito rappresenta la risposta a quella particolare combinazione di sottodomande.
Stile delle domande
E' possibile modicare lo stile/layout generale delle domande utilizzando i files CSS. Per approfondire: styling questions with CSS
Tipologie di domande
Arrays o Matrici
Le tipologie "Array", permettono di visualizzare una matrice per ciascuna domanda, in cui generalmente ciascuna riga rappresenta una sottodomanda, mentre ciascuna colonna corrisponde ad un'opzione di risposta. Il testo della domanda in questo caso può contenere un quesito specifico, oppure può fungere da descrizione/istruzione per la compilazione della matrice stessa.
In termini di output, verrà creata una variabile per ciascuna sottodomanda, alla stregua di una domanda del tipo "Pulsanti Radio".
Le tipologie più flessibili di domanda a matrice sono "Array","Scelta (Testi)" e "Array (Numeri)". Esistono poi altre tipologie precodificate che facilitano l'inserimento.
Array
Si tratta della versione base, in questo caso una volta selezionata la tipologia "Array", dovranno essere inserite:
- una lista di sottodomande che verranno visulizzate nelle righe della matrice - una lista di risposte che verranno visulizzate nelle colonne. In sostanza, l'intervistato dovrà selezionare per ciascuna sottodomanda una delle opzioni indicate in colonna.
Array (5 point choice)
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.
