Sexual harassment on the Internet In his statistics course project, a student stated “Millions of Internet users engaged in online activities of sexual harassment”. This conclusion was based on a survey administrated through different social media networks, in which 2% of the respondents reported they had sexually harassed someone online. In such a study, explain how there could be

a. Sampling bias. (Hint: Are all Internet users equally likely to respond to the survey?)

b. Nonresponse bias, if some users refuse to participate.

c. Response bias, if some users who participate are not truthful.
