Abstract: The purpose of this paper is to point out differences in the answers of paper and web questionnaires and to recommend what to consider when using web questionnaires in mixed mode surveys. These recommendations can be useful when implementing web questionnaires. A problem with mixed mode surveys is that the diverse methods have generated different answers. To investigate this further we have conducted a survey consisting of one paper questionnaire and two web questionnaires, involving 90 respondents. To test our collected data we have used a Test of Homogeneity- Pearson?s Chi square test (X?) and ANOVA tests. The result of this study shows that there are differences between the methods. Based on the differences we present recommendations how to facilitate the use of web questionnaires in mixed mode surveying. The recommendations are based upon the importance of usability and how to design a web questionnaire.
