Quota check

Quota check lets you inspect quota fulfilment status at any point in the survey flow. Unlike other survey flow controls, it is entirely informational and does not redirect, terminate, or otherwise affect the respondent’s path on its own. If you want to act on quota status (such as to screen-out, redirect, etc.), you must set that up separately by referencing it in display logic, specific survey flow controls, or formulas in subsequent questions.

What does Quota check do?

The Quota check provides two outputs:

1. Quota status (TRUE/FALSE):

   • Returns TRUE if the respondent is over quota (i.e. the quota is already full).
   • Returns FALSE if the respondent is under quota (i.e. the quota is not yet full).

2. Quota counter:

   • Outputs the respondent’s sequential quota number (essentially a running counter for that quota).
   • Accessible via the sequentialNumber function for use in calculated variables or pipe-in formulas.
   • Please note that the quota counter is cached for 60 seconds, so some respondents may receive the same sequential number if they reach the Quota check within the same caching window.

Using Quota check outputs

In display logic

You can use the Quota check output in display logic to conditionally show or hide questions depending on quota status. For example:

• Show a bonus question only if the respondent is within quota (FALSE).
• Display a different message if the quota is full (TRUE).

In formulas

The sequentialNumber function can be used in calculated variables or pipe-in formulas to perform calculations or assign respondents to different groups based on the respondent’s position in the quota sequence.

Adding a Quota check

To add a Quota check to your experiment:

1. Navigate to the Add questions tab.
2. Click on the Add question button at the bottom of the page.
3. In the Add or import questions pop-out, select the Add a flow control or a block tab.
4. Click on the Quota check card.

Once added, configure the following fields:

• Quota: Determine the number of participants who bypass the quota check. These respondents always return FALSE (under quota) and are not counted toward quota fulfilment.
• Trigger this control if: Define conditions under which this quota check is activated. If left empty, the quota check applies to all respondents reaching this point in the survey flow.

Please note that Quota check does not alter the respondent’s survey path on its own. To act on the quota status, ensure it is referenced in display logic or formulas in subsequent questions.

FAQs

Is it possible to place this question inside a block?

This question can be used only within the following blocks due to complications and uncertainties when displaying it with the stimuli or conjoint sets (consistent with other flow controls):

• Simple block
• Randomisation block
• Screening block
