Sampling - Solutions Activity 1.1 Non-response bias refers to a bias that occurs if people with a particular opinion or trait tend to refuse to answer certain survey questions (or possibly refuse to participate in the survey at all). Response bias refers to the systematic effect of false answers given by survey participants. Suppose the office that does the Penn State Pulse surveys does a survey about the frequency of academic cheating (and they have!). In the context of such a survey about cheating, explain the difference between nonresponse bias and response bias. Non-response: perhaps those who cheat a lot won’t answer questions, or will refuse to be in the survey. Response: perhaps those who cheat a lot will lie about their cheating. 1.2 Suppose you want to sample the music of a band you haven’t heard before. You’re given 5 CDs, each with 12 tracks. You’ll use a probability method to sample 5 tracks to play. a. Describe (briefly) how you would carry out a simple random sampling method to pick the 5 tracks.
