- Excel Editor
- Online Editor
The excel editor is most suited to larger complex surveys. It also allows editing without an internet connection.
The online editor is quicker and simpler than the excel editor but harder to use for large complex surveys. It also can be unreliable when moving questions within the survey, particularly if this is to and from groups. If you enclounter any problems when moving questions export the survey to excel, do the move there and then load the excel survey back onto the server.
Surveys can be as small as 1 question. There is no specified maxiumum size, one customer completed a survey that had over 4,500 questions. However surveys used for evaluations commonly have around 300 questions. Surveys used for monitoring would usually be shorter.
Although there is no limit to the size of surveys we can only store the answers for 1,600 questions in a form. So if you have more questions you will need to put them into multiple forms. This can be done so that the data collector and analyst are unaware that the survey has been split up.
- Put around 1,500 questions in the main form (Leaving a bit of room for expansion later)
- Then specify a subform using the "begin repeat" question type and with a repeat_count of "1"
- Put the next 1,500 questions in this subform
- Repeat until all questions have been added
To allow all the data to be exported together each new subform should be create in it's parent subform as shown below:
- -- Main Form
- -- Subform 1
- -- Subform 2
However you can also load surveys in an XML XForm format. These can contain sophisticated functionality that is not supported by the above two editors. If you have a survey in XML format then you can load it onto the server in the same way you would load a Survey created with Excel. Creating a survey in XML
We use the terms "Survey" and "Form" interchangeably. However more precisely there can be multiple forms in a survey. These consist of a main form where you start answering questions and zero or more repeating sub forms. For example the main form may ask questions about a household while a sub-form asks questions to be answered for each member of the household.
