Expand All A Collapse All Introduction Sample design is very important, as we saw in the U.S. 2000 presidential election, where Florida was initially declared for the Democratic candidate based on a sample that did not truly reflect the entire state. Careful consideration must be paid to ensure a representative sample if we are inferring those results on a population. Locate & Complete Have you seen or read about an example where data were presented on an issue, but the sample was not representative of the population from which it was drawn? If you can't recall a specific example, locate one using an Internet search. For this discussion, summarize the issue and respond to the following questions. • Why do you believe the sample was not representative of the population? What are the undesirable consequences of using a poor sampling technique? How could the inaccurate reporting of the data been prevented? . . Your initial response should be four paragraphs in length.

Poll Reveals Who's Most Vaccine-Hesitant in America and Why By Cara Murez HealthDay Reporter THURSDAY, April 29, 2021 (HealthDay News) -- U.S. resistance to getting a COVID-19 vaccine is slowly diminishing, a new online survey finds, but it still exists and at especially rates in some blue-collar jobs. For adults under age 65 who are hesitant, reluctance is mainly driven by concerns about safety, side effects and distrust in government, the poll found. It's also largely linked to people's line of work. The bottom line: "Vaccine hesitancy is emerging as a key barrier to ending the COVID-19 pandemic," said lead author Wendy King, associate professor of epidemiology in the University of Pittsburgh Graduate School of Public Health. Identifying occupations with a high rate of vaccine hesitancy and understanding the reasons for it might help public health workers address concerns, she said. "Our study indicates that messaging about COVID-19 vaccine safety and addressing trust are paramount," King said in a university news release. King and researchers from the Delphi Group at nearby Carnegie Mellon University analyzed results from its ongoing COVID-19 survey in collaboration with the Facebook Data for Good group. About 1.2 million U.S. residents in Facebook's active user database complete the survey each month.

In January, the survey added a question about willingness to receive the vaccine. This study was limited to working-age adults, because workplace outbreaks and spread of infection from workers to customers are public health threats. Many working-age adults also are more hesitant about getting a shot than older Americans. While resistance persists, there was some encouraging news: Vaccine hesitancy fell from 27.5% in January to 22% in March, according to the survey. The March survey included 732,308 people (median age: 35 to 44, meaning half were older, half younger). About 45% were male, 77% had some college education and 64% were white. Nearly 48% of those who reported vaccine hesitancy expressed concern about side effects. More than one-third didn't think they needed the shot, didn't trust the government, were waiting to see if the vaccine was safe or didn't trust COVID-19 vaccines specifically. And 14.5% said they didn't like vaccines in general. Workers in some occupations were more reluctant than others to take the jab. Hesitancy ranged from 9.6% among educators and people in life, physical or social sciences to a high of 46% among workers in construction, oil and gas extraction and mining. Hesitancy was nearly as high among workers in installation, maintenance, repair, farming, fishing or forestry. In health care fields, pharmacists were the least hesitant at 8.5%. The highest hesitancy, 20.5%, was among medical assistants, emergency medical technicians and home health, nursing, psychiatric or personal-care aides. "The survey has grown to collect data on symptoms, illness, treatment, testing, behaviors like masking and distancing, and mental health," said senior author Robin Mejia, from Carnegie Mellon's Dietrich College of Humanities and Social Sciences. "And it's continuing to evolve as new policy questions arise." The survey results were posted April 24 on the preprint server medRxiv and have not been peer- reviewed.

How accurate are online polls? By Michael Suh Q. How statistically accurate is an online poll in which participants sign on to contribute their opinions? Would it be possible to get statistically accurate opinions about what the average American wants thei taxes to go to through an online poll that allows the participant to indicate what percentage of his/her taxes would go for each of a number of purposes? The accuracy of a poll depends on how it was conducted. Most of Pew Research's polling is done by telephone. By contrast, most online polls that use participants who volunteer to take part do not have a proven record accuracy. There are at least two reasons for this. One is that not everyone in the U.S. uses the internet, and those who do not are demographically different from the rest of the public. Another reason is that people who volunteer for polls may be different from other people in ways that could make the poll unrepresentative. At worst, online polls can be seriously biased if people who hold a particular point of view are more motivated to participate than those with a different point of view. A good example of this was seen in 1998 when AOL posted an online poll asking if President Clinton should resign because of his relationship with a White House intern. The online poll found that 52% of the more than 100,000 respondents said he should. Telephone polls conducted at the same time with much smaller but representative samples of the public found far fewer saying the president should resign (21% in a CBS poll, 23% in a Gallup poll, and 36% in an ABC poll). The president's critics were highly motivated to register their disapproval of his behavior, and this resulted in a biased measurement of public opinion in the AOL online poll. The American Association for Public Opinion Research recently released a detailed report on the strengths and weaknesses of online polling. The full text of the report can be found here. Keep in mind that there is nothin inherently wrong with conducting surveys online; we do many of them with special populations such as foreign policy experts and scientists. And some online surveys are done with special panels of respondents who ha been recruited randomly and then provided with internet access if they do not have it. You also ask whether online polling could determine how Americans would like to see tax revenue spent. Theoretically it could. Because of the complexity of the federal budget, any such poll would have inherent limitations, of course. And an online poll that people volunteered for would have the same potential flaws as other online polling. Scott Keeter, Director of Survey Research, Pew Research Center
