It is easy to ask a question in a small or large text box, or for the participant to have the option of choosing more than one alternative. He uses a scale. I know of no other program that is simpler to use to create construction surveys. It is simple to export to programs such as SPSS or Excel, which can be used. Senja incorporates some variables that are not relevant for my research purposes (such as IP code and other random numbers), but it is simple to eliminate them. When a questionnaire is emailed through Senja, it looks professional and modern. It is very pleasing to the reader.
