Computers and the Internet are an efficient as well as a comfortable and attractive way for respondents to complete questionnaires. The CAWI (Computer Aided Web Interviewing) data collection method has become increasingly popular. Respondents can answer the questions either at home or in their workplace, even with several interruptions. The CAWI questionnaire appears in the browser as a web-page that respondents can reach in different ways depending on the sample design. The questionnaire is designed to enable respondents to enter responses directly into the computer and the program guides them through the questionnaire. The answers from the questionnaire get immediately to the main server so the data collection and the results can be tracked continuously.
This is a particularly useful method for business-to-business respondents, who tend to regard an interviewer's presence in their offices as somewhat disruptive to their schedule, but they are willing to respond, within a given time-frame.
Great advantage of this method include rapidity, possibility to track the data all the way, intergration of multimedia materials, fast correction of mistakes and cost-effictivity.
The selection of respondents is based on the specification of concrete order covering representative sample of the Czech population or selected segments of the population.
