apply if

Quota variables are, in large part, intended to be totally inclusive. In the vast majority of circumstances, it is most sensible to program them such that every survey respondent qualifies for a bucket. This practice ensures that no gaps exist which allow respondents to get through quotas unintentionally. For this reason, the default behavior within IntelliSurvey is to terminate all respondents who fail to qualify for any bucket at a quota variable. In case it is necessary to have quotas on a page which does not have exhaustive buckets for all respondent groups, use the apply if tag. In order for a respondent to punch a quota bucket (or fail to, and be sent to over-quota), the condition specified at apply if must be met. If it is not met, the respondent simply skips over the quota, without regard for whether or not they qualify for any open bucket, or none at all.

Syntax

QUOTA. This is a quota
type: quotas
applyif: Logical statement defining a respondent subset
1. Option A
2. Option B

Example

Suppose an ethnicity question is asked to the subset of respondents with a punch of code 1 at the variable QCOUNTRY:

COUNTRY. Respondent Country
invisible: y
type: radio
cvalue: url_param('c')
1. USA
2. Canada
3. Mexico
 
...
 
2. What is your race or ethnic background? 
showif: anyChecked($QCOUNTRY,1)
type: radio
1.	White or Caucasian
2.	Black or African American
3.	Asian
4.	American Indian, Alaska Native, Native Hawaiian or other Pacific Islander
97.	Some other ethnicity {autoother: y; placeholder: Specify}

The following quota is placed later in the survey, and is based on the aforementioned ethnicity question, Q2:

RACE. QUOTA | Race-Ethnicity
type: quotas
applyif: anyChecked($QCOUNTRY,1)
optsfrom: Q2

Respondents from Canada or Mexico would not be subject to this quota.
