Instructional Questions:
Let’s start with the instructional questions. As the name implies, instructional questions simply give information or instructions to people taking the survey. Instructional questions could also explain some of the background to the survey. They do not load any data into the data file.
Special Questions:
Special questions are not seen by a respondent, but they do load data into the data file. Usually this data comes from an address file and often includes “pre-populated” data – existing data that you already have about that person such as their demographics or past purchases of products.

How to Run a 2-in-1 Survey
If you have several surveys with common questions and, in addition, have extra questions specific to one group of people, you can set up a single-question file with all the questions and then use skips or avoids to ensure that people only see the questions applicable to their situation.
When would you use a 2-in-1 survey like this? It depends on the specific situation, but take an example of surveying a club or association membership list. Some questions would be common to everyone, but you may have questions that apply to only country vs. town members or professional members vs. amateur members. Use data from a previous question or from data imported in the address file to guide the survey. In general if more than 2/3 of the questions are common to each, it’s probably worthwhile to combine the surveys into a 2-in-1 survey.

In The Survey System terms, this is called “Interview Logic.” Each question in a question file has an “Interview Logic” button. Clicking on this will show all the logic variants available. These vary according to the kind of question. The simplest (and the first in the list) is the “Skip” variant, which allows you to instruct the program to go directly to a specific question rather than next one in the file.
