Chapter 4: Problem 83

Internet poll Find an example of results of an Internet poll. Do you trust the results of the poll? If not, explain why not.

Short Answer

Expert verified
Evaluate the poll's source, methodology, and potential biases to determine trustworthiness.

Step by step solution

01

Researching an Internet Poll

To start, we search online for a recent example of an Internet poll. Let's say we find a poll that reports 55% of participants prefer shopping online versus in-store.
02

Analyzing the Poll's Source

Check the source of the poll. If it's from a reputable organization with a history of accurate polling, it may be more trustworthy than a poll from an obscure website.
03

Examining Methodology

Look into how the poll was conducted. Consider factors such as how participants were selected, the sample size, and whether it was random. These factors affect the poll's reliability.
04

Checking for Bias

Identify any potential biases. This could include leading questions or a non-representative sample, such as only surveying people from a specific demographic.
05

Evaluating the Results' Validity

Consider whether the results are consistent with other recent polls on similar topics. If they are drastically different, this could indicate issues with the poll's reliability.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Poll Reliability
Reliability in polling refers to how consistently a poll can produce accurate results that reflect the true sentiment of the population. Understanding and evaluating poll reliability require a look into several factors:
  • Source Credibility: Reliable polls usually come from well-known and respected organizations with a track record of accurate predictions. Always double-check the pollster's reputation and history.

  • Consistency: Compare the poll's results with those of other polls on the same topic. If the results align with others, it increases reliability. If they are outliers, there might be an issue with reliability.

  • Sample Size: A small sample size can lead to unreliable results because it may not adequately represent the wider population. Larger sample sizes tend to yield more reliable results.

  • Question Wording and Order: How questions are phrased and the order in which they are asked can significantly affect the responses. Leading or ambiguous questions can skew reliability.
Survey Methodology
Survey methodology is a crucial aspect of any internet poll, as it outlines how the poll is administered and analyzed. Key considerations include:
  • Participant Selection: Selection methods, like random sampling, are vital. Random samples generally cover a diverse range of responses, boosting the survey's representativeness.

  • Data Collection: Consider whether the survey was conducted online, by phone, or via face-to-face interactions. This can impact how willing respondents are to answer honestly and affect the final data collected.

  • Survey Design: A well-designed survey will be clear and concise. Complexity or ambiguity can confuse participants and compromise responses.

  • Sampling Method: The method of selecting participants plays a pivotal role. Random sampling is ideal, but other methods, like voluntary response sampling, can introduce bias.
Sampling Bias
Sampling bias occurs when the sample used does not accurately represent the whole population. It is a critical concern in internet polls, which often use non-random sampling methods. Key elements to understand and mitigate sampling bias include:
  • Representative Sample: Ensure the sample includes diverse demographic groups to accurately reflect the entire population.

  • Self-selection: Internet polls may be susceptible to self-selection bias, where only those with a strong opinion on the topic participate, skewing results.

  • Exclusion of Groups: If certain groups are underrepresented or excluded, such as younger or technologically-challenged participants, it could lead to bias.

  • Geographic Representation: A skew in regional representation can introduce bias if the views are significantly different across regions.

In a follow-up study, 103 patients in the Netherlands having warts were randomly assigned to use duct tape or a placebo, which was a ring covered by tape so that the wart itself was kept clear \((\) Arch. Pediat. Adoles. Med. \(2006 ; 160: 1121-1125)\) a. Identify the response variable, the explanatory variable, the experimental units, and the treatments. b. After six weeks, the warts had disappeared for \(16 \%\) of the duct tape group and \(6 \%\) of the placebo group. However, the difference was declared to be "not statistically significant." Explain what this means.

Beware of online polls According to an online poll, \(46 \%\) of Americans support Apple Inc.'s decision to oppose a federal court order demanding that it unlock a smartphone used by one of the culprits responsible for the San Bernardino terrorist attacks. Mention a lurking variable that could bias the results of such an online survey, and explain how it could affect the results.

There have been anecdotal reports of the ability of duct tape to remove warts. In an experiment conducted at the Madigan Army Medical Center in the state of Washington (Archives of Pediatric and Adolescent Medicine \(2002 ; 156: 971-974)\), 51 patients between the ages of 3 and 22 were randomly assigned to receive either duct-tape therapy (covering the wart with a piece of duct tape) or cryotherapy (freezing a wart by applying a quick, narrow blast of liquid nitrogen). After two months, the percentage successfully treated was \(85 \%\) in the duct tape group and \(60 \%\) in the cryotherapy group. a. Identify the response variable, the explanatory variable, the experimental units, and the treatments. b. Describe the steps of how you could randomize in assigning the 51 patients to the treatment groups.

Mean family size You'd like to estimate the mean size of families in your community. Explain why you'll tend to get a smaller sample mean if you sample \(n\) families than if you sample \(n\) individuals (asking them to report their family size). (Hint: When you sample individuals, explain why you are more likely to sample a large family than a small family. To think of this, it may help to consider the case \(n=1\) with a population of two families, one with 10 people and one with only 2 people.)

You would like to investigate whether smokers are more likely than nonsmokers to get lung cancer. From the students in your class, you pick half at random to smoke a pack of cigarettes each day and half not ever to smoke. Fifty years from now, you will analyze whether more smokers than nonsmokers got lung cancer. a. Is this an experiment or an observational study? Why? b. Summarize at least three practical difficulties with this planned study.
