quota tracking variable

The quota tracking variable tag is used to specify the name of a variable for tracking the over quota punches for quotas created with the type: quotas and quotabase tags. This is most commonly used in click balance quotas (CBQs) but can be used for other sampling needs and quota structures, too. For example, regular quotas (quotas used to track "completed" respondents) use the oq variable for tracking over quota punches. Similarly, a CBQ would use the quota tracking variable tag to create a separate variable called cb in order to insulate the click-balancing quota data from the regular quota data.

Note: This tag is only used with type: quotas and quotabase. The newer, simplified method for creating CBQs using the click balance quota tag or type: click balance quota generates the tracking variable cboq by default. The quota tracking variable tag cannot be used with the newer method to alter this variable name.

If you are creating click balancing quotas for your survey, please consider using the newer method described in the Click balance quotas article.

Syntax

The quota tracking variable tag is put directly on a quota widget (type: quotas). It applies to that widget only, but multiple quota widgets can use the same variable. In absence of this tag, the default variable used to store any over quota data is oq.

P1_QUOTA. Quota Variable
type: quotas
quotatrackingvariable: cb
quotabase: anyChecked...
1. Option 1
2. Option 2
etc.

Note: At this time, the quota tracking variable tag input is restricted to cb.

Example

This is an example of a click balancing quota created using the quota tracking variable, quotabase, and status if over tags. quotabase specifies the criteria required for respondents to count towards the quota; status if over specifies the custom status (defined via set status) for respondents failing to qualify for the CBQ, and the quota tracking variable specifies the reporting variable cb to use to store the over quota data.
