A standard, rule, or test on which a judgment or decision can be based. When designing surveys there may be questions that need to be displayed only if certain conditions are met. Similarly we may also want to create reports based on certain conditions / criteria.
For Example:
IF Gender = Male
AND
Age = 18 Or Above
Display Question 5.
ELSE
Jump to Question 6.
Here the Criteria for displaying Question 5 is that respondent needs to be a Male Adult.
