The data set is based on a questionnaire on attitudes towards the Internet. It consists of evaluations of 22 statements about the Internet by 281 students at Erasmus University Rotterdam. These data were gathered around 2002 before the wide availability of broadband Internet access in the Netherlands. The statements were evaluated using a seven-point Likert scale, ranging from 1 (completely disagree) to 7 (completely agree).
