A university wants to survey its undergraduates about their satisfaction with the new website. The university researchers pasted a link to the survey on the new website. A majority of the surveys showed that students were happy with the new website and found it easy to use. The university concluded that the website was fine and did not make any changes. However, on Friday, hundreds of students turned up at the Undergraduate Student Committee meeting complaining about how difficult it was to navigate the new website. University researchers realized that placing the survey on the website meant that people who liked the website were more likely to access the survey. Which of the following types of bias affected the survey's conclusions? 1. Non-response bias
2. Selection bias
3. Deliberate bias
