Survey quotas/nl

Uitleg

Met een quota kun je het aantal keren beperken dat een actieve enquête wordt ingevuld. Je kunt hier kijken naar verschillende kenmerken van de respondent zoals geslacht of leeftijd.  Een quota kan worden toegevoegd, gewijzigd of verwijderd met de keuze Quota's onder de keuze Enquête eigenschappen op de Enquête toolbar.

Er is een voorbeeld enquête, in het Engels, waarin het gebruik wordt uitgelegd. Je kunt deze enquête importeren met de knop importeer gegevens op de enquête aanmaakpagina. Voorbeeld enquête met quota's

Quota's sluiten niet automatisch uit

Quota's zijn niet uitgebreid en automatisch uitsluitend. Een voorbeeld, je hebt een enquête met een Ja/Nee vraag.

Je stelt een quota in dat je maximaal 20 responses wilt hebben op deze vraag met Ja antwoorden. De quota controleert of er Ja wordt ingevuld en of de gehele enquête wordt ingevuld. Als er 20 zijn, dan komt er een quota actie als er nog iemand Ja kiest. Iemand die Ja kiest en niet de enquête helemaal invult, telt niet mee voor de quota.

Echter, als iemand Nee kiest, dan kan de enquête gewoon worden ingevuld.

Je kunt natuurlijk wel ook een quota zetten op het aantal responses die Nee kiezen.

Supported question types

Currently only the following question types can have a quota defined for it:

• Gender
• Multiple Choice
• Array - 5 Point Choice
• Array - 10 Point Choice
• Language Switch
• Yes/No
• List (Radio)
• List (Dropdown)
• List with comments

Example of a quota

You might have to conduct a survey where you want to limit it to 25 male and 30 female respondents. You could then define a quota with a limit of 25 for the answer "Male" from your gender question in the survey.  Another quota for the answer "Female" with a limit of 30 could be added as well.  This will give you a maximum of 25 males who will be able to complete the survey, and a maximum of 30 females who can complete the survey.

A survey participant has to match all answers under the quota for it to apply to that response.

Adding a new Quota

Adding a new quota is really adding a framework for set of quota conditions. For a fully working quota you must firstly "Add a quota", and then "Add Answers" to that quota (see next section).

When adding a quota, you will be asked for a "Quota Name", the "Quota Limit", and a "Quota Action".

From version 1.85RC you will also have the option of setting your own unique quota "Quota Message", "url" and "URL Description" for each language used in your survey. You can also set "Autoload URL" so that the survey redirects users to the quota URL when the quota action is triggered.

All new quotas are assigned to the Survey you were viewing when you clicked "Set Survey Quotas".

• Quota Name: This is a name to reference the quota by, generally it should describe the quota it will represent.
• Quota Limit: This is maximum number of completed surveys to allow for the quota. This sets a limit that will be check when quota selected questions are answered during the survey.
• Quota Action: This is an action to perform when a participant is filling out a survey and lands up being part of a quota that has become full.
  • Terminate Survey: This immediately terminates the survey, and closes the interview.
  • Terminate Survey With Warning: This warns the participant and allows them to go back
• Autoload URL: This tells LimeSurvey to automatically redirect the participant to the URL when the quota action occurs. (Only In Version 1.85RC)
• Quota Message: The text displayed to your survey participant if the quota action is triggered (ie: the quota is full). (Only In Version 1.85RC)
• URL: The URL displayed to survey participants after the quota message, or the URL participants are automatically redirected to if 'Autoload URL' is turned on. You can use URL fields in this section. (Only in Version 1.85RC)
• URL Description: The text displayed for the URL. (Only in Version 1.85RC)

Once a quota is added, you will be able to add answers under the quota.

Adding an answer

• Select Question:

+When adding a answer under the quota, you will be shown a list of all available quota questions which are in your survey. If a question does not show up on the list, then its not yet supported with quotas. After you have chosen the question you want, press "Next" to move on to answer selection.

• Select Answer:

+Once selecting your question, you will be show a list of answers under that question. Here you will select an answer you would like to add to you quota, then press "Next".

Adding multiple quotas for the same question & subquestion

Adding multiple quotas for the same question is surely possible - but  know that quotas are checked with a logical 'AND' operator - so to meet the quota the user has to answer both subquestion in that question like in your quota.

This means also that multiple quotas for the same subquestion or the same single choice question can never come true.

Quota and response data

All data is saved when the participant clicks the "Next" button. Even if the quota is full, the data submitted until the survey is terminated will be recorded. Nevertheless, such id is marked as "No Completed".

Quota and tokens

When tokens are used in a survey and the user is screened out due to a quota, then the according token entry is marked with the letter "Q" in the Completed column. That way the token is invalidated and the survey participant can't re-start the survey.
