Filters help you produce more sophisticated reports. There are two types of filters:
Demographic Filters enable you to choose a specific group that you may be interested in (e.g Females aged 18-29) and create a different report to look specifically at that group. Gorkana Surveys automatically shows other groups it thinks you will be interested in, in this case Males aged 18-29. This enables you to view relevant comparisons quickly and easily.
Question Filters enable you to choose an answer to one question (i.e. Do you have a mobile phone? - Yes) and see the other answers in the survey filtered only by those who said yes.
