Defining expression quotas
1 Click the Expression Quotas tab.
2 Drag a variable from the List Pane onto the Expression Quotas tab.
The Filter On dialog opens.
3 Define the quota characteristics and selection criteria. See:
Categorical variables
Numeric variables
Text variables
Boolean variables
4 If the expression is based on two or more variables or values, click Next; otherwise, click Finish. See Expression quotas using two or more variables.
The quota appears on the Expression Quotas tab with a unique name and a default target of 100.
5 In Target, type the target you want to set.
6 In Type, choose one of the following:
Option
Description
Normal
This is an ordinary quota, so the sum of pending and completed interviews for this quota must never exceed the target. Once the sum of pending and completed interviews for this quota matches the target, all subsequent interviews for this quota fail. If any of the pending interviews do not complete, further interviews will be required to meet the target.
Allow over
Allow the sum of pending and completed interviews for this quota to exceed the target. New interviews can be started for this quota until the number of completed interviews matches the target. If all the pending interviews complete, the target might be exceeded. Once the target has been met, any new interviews for this quota fail the quota test and are dealt with as specified by the scriptwriter (usually the interview terminates).
Counter
There is no target for this quota, so there is no quota control, but the number of respondents belonging to the quota is counted.
7 In Description, type a description of the expression.
8 Click File > Save.
You must give the .mqd file the same name as the project and save it in the project’s source directory; otherwise the activation process fails when the scriptwriter tries to activate the project.
