Design of Web Surveys

Principles of Design for Web Questionnaires (Dolman, Tortora, Bowker)

• Welcome screen• First question should be easy to answer,

but interesting• Conventional format similar to paper• Limit line length• Provide instructions for computer

actions

Principles of Design for Web Questionnaires (Dillman, Tortora, Bowker)

• Instructions with individual questions, not at the beginning

• Do not force answers unless necessary• Scrolling• Progress bar

Principles of Design for Web Questionnaires Dillman, Tortora(, Bowker)

• Screen by screen– Only one question per page, respondent must

answer the questions before they can continue

• Scrolling – Respondent can see, if not the entire questionnaire,

more than one question.
