Computer-assisted web interviewing (CAWI) is a Internet surveying technique in which the interviewer follows a script provided in a website. The questionnaires are made in a program for creating web interviews. The program allows for the questionnaire to contain pictures, audio and video clips, links to different web pages, etc. The website is able to customize the flow of the questionnaire based on the answers provided, as well as information already known about the participant.

It’s considered to be a cheaper way of surveying since you don’t need to use people to hold surveys unlike Computer-assisted telephone interviewing.

With the increasing use of the Internet, online questionnaires have become a popular way of collecting information. The design of an online questionnaire often has an effect on the quality of data gathered.
