Matrix-Ausschlussfilter

Beschreibung

Mit der Einstellung "Matrix-Ausschlussfilter" können Sie eine beliebige Multiple-Choice-Frage verwenden, um auszuwählen oder festzulegen, welche Antwortoptionen in einer nachfolgenden Liste, einer AMtrix oder einer Multiple-Choice-Frage NICHT angezeigt werden.

Es können die nachfolgenden Fragetypen gefiltert werden auf Basis jedes Matrix-Fragetypen, inklusive:
  • Mehrfachauswahl
  • Mehrfachauswahl mit Kommentaren
  • Mehrfache kurze Texte
  • Mehrfach numerische Eingabe
  • Matrix (5 Punkt 10 Punkt, Ja/Nein/Unbekannt, Abnahme/Gleich/Zunahme, Nach Spalte)
  • Matrix (Doppel-Skala, Text, Zahlen)
  • Reihenfolge

Außerdem kann jeder dieser Fragetypen an sich gefiltert werden.

Die einzige Ausnahme ist der Matrix (nach Spalte)-Fragetyp, der andere Fragen filtern kann, aber selbst nicht gefiltert werden kann.

Einrichtung

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.

Beispiel

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.
