Question

Read the article by Horvitz et al. (1995) on Self-Selected Opinion Polls, which they term SLOPs. Find an example of a SLOP and explain why results from the poll should not be generalized to the population of interest. Find a recent survey reported in a newspaper, academic journal, or popular magazine. Describe the survey. What are the target population and sampled population? What conclusions are drawn about the survey in the article? Do you think those conclusions are justified? What are possible sources of bias for the survey? Find a survey on the Internet. For example, Survcy.Net allows you to participate in surveys on a variety of subjects; you can find other surveys by searching online for "survey" or "take survey." Participate in one of the surveys yourself, and write a paragraph or two describing the survey and its results (most online surveys allow you to sec the statistics from all the persons who have taken the survey). What are the target population and sampled population? What biases do you think might occur in the results? Some polling organizations recruit volunteers for an Internet panel and then take samples from the panel to measure public opinion. Volunteer to be in an Internet panel for a survey organization (search for "online poll" to find one). What information are you asked to provide? Report how the organization produces estimates. At about the same time Hite (1987) conducted the survey described in Section 1.1, a survey on similar topics was taken in the United Kingdom. Read the article by Wadsworth et al. (1993) describing the National Survey of Sexual Attitudes and Lifestyles. How do the authors describe potential biases and sources of error in the survey? Contrast the possible errors in this survey with those in Hite (1987).

Explanation / Answer

28. I found a poll in imdb for chosing the coolest marvel superhero of all time. In this, survey, I voted for wolverine. The number 1 position according the results goes to deadpool and wolverine is at number 2 position. There were 35 options given to chose from. But the survey didnt include some superheroes, say for example: spiderman. Here, the survey is supposed to target all the movie audiences, but only the people who are interested in superhero movies will chose to vote in the survey, and hence there will be a bias. The survey might also get affected because of the recent success of the deadpol movie and the upcoming Wolvewrine movie. Meaning, if the survey was done at some other point of time, we might have got a different result. The sample of the survey as of now is 4400 votes. The survey also doesnt give an option for the voter to chose 'others' or to add anymore characters to the given list
