Allowing multiple choices is not advised or supported, because it makes the reporting much less useful.
When people can choose multiple items, the reports deteriorate in two ways:
1. People no longer indicate the first or most salient way they learned about the project. So this information is no longer captured in the report and available for marketing decisions.
2. Person A may choose one answer, (even if they've noticed multiple media), while Person B may choose 3 answers. Although the choice made by Person A is just as relevant, it gets lost in the multiple answers chosen by Person B. Again, this makes the report less useful.
3. More technically inclined people will figure out how to make multiple choices, while less technically inclined people will not figure this out (whether directions are given or not). Again this will skew the report results towards the answers of the more technically inclined.
Finally, if we are asking people to take the time to choose multiple answers, we are using up their valuable time, time which could be used to answer a different question (i.e. bedroom/price range etc). In other words, we would get more benefit from asking a different question than asking for more detail on the one question.
For these reasons, Intersoft does not advise nor support multiple choice questions.
