In \(2015,\) the National Drowning Report published in Australia shows a drowning rate of 0.26 per 100,000 people in the Australian Capital Territory \((\mathrm{ACT})\). A few days ago, you read about a teenager who drowned in the middle of the sea in the \(\mathrm{ACT}\). In deciding whether to go to the \(\mathrm{ACT}\) for a beach holiday with your best friends, should you give more weight to the study or to the news you have recently read about a teenager who drowned? Why?

Short Answer

Expert verified
Give more weight to the statistical study as it provides a reliable risk assessment over time, unlike the news of a single incident.

Step by step solution

01

Understand the Context

The exercise involves understanding how to interpret statistical data and anecdotal evidence (i.e., news of a recent incident) when making a decision about safety.
02

Review the Drowning Rate

The National Drowning Report indicates a drowning rate of 0.26 per 100,000 people in the ACT in 2015. This is a statistical measure based on historical data and reflects the probability of drowning as a general risk.
03

Consider the Anecdotal Evidence

The recent news of a teenager who drowned represents an anecdotal event. It's a single incident and might not reflect the general safety conditions or the likelihood of accidents within the region.
04

Compare Statistical Data and Anecdotal Evidence

Statistical data gives a broader overview of risks over some time and is a more reliable source for making decisions. Anecdotal evidence, though impactful, represents only an isolated instance and does not affect the overall statistical risk.
05

Make a Decision Based on Evidence

In deciding whether to give more weight to the study or the news, consider that the former provides a comprehensive view based on long-term data, while the latter is a single case. Therefore, statistical data should be given more weight in deciding the general safety of visiting ACT for holidays.

Key Concepts

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

Interpreting Data
When faced with decisions involving safety or risk, interpreting data becomes essential. Statistical reasoning helps us see the bigger picture by examining patterns and frequencies rather than isolated incidents. In the case of the ACT's drowning report from 2015, the reported rate was 0.26 drownings per 100,000 people. This statistic is derived from a data set that likely covers several years and numerous events, giving it reliability and a scope that a single news story cannot provide.

It's important to understand that statistical data, like this drowning rate, provides a broader and more stable perspective. It factors in numerous variables and occurrences over time, which allows us to form a clearer picture of the actual risks involved.

Relying solely on one-off news stories, such as hearing about a single drowning incident, can lead to skewed perception. Such anecdotes can amplify fears without reflecting the true likelihood of similar events occurring.
Risk Assessment
Risk assessment involves analyzing and weighing the probability and impact of potential negative outcomes. In terms of drowning risks at the ACT, the statistical data provides a basis for assessing the risk. With a rate of 0.26 per 100,000, this suggests that drownings are relatively uncommon.

To effectively assess risk, one should understand the context of where this data comes from:
  • Number of people who visit the ACT beaches each year.
  • Frequency of reporting and historical consistency of such data.
  • Comparison of drowning rates with other regions or activities.
These variables help paint a complete picture and allow for a more informed assessment of potential risks. Simply reacting to a recent, singular incident might overshadow these broader findings. That is why risk assessment should focus more on statistical evidence rather than isolated anecdotes.
Decision Making
Decision making is about choosing the most rational option based on available information. In this exercise, deciding on whether to visit the ACT for a beach holiday involves evaluating the statistical data versus anecdotal news.

Here's how you can approach this decision-making process:
  • Evaluate the reliability of the data source. The National Drowning Report is a systematic collection of data which typically ensures accuracy over time.
  • Consider the emotional impact of anecdotal evidence. Stories of recent incidents might seem alarming, but it's crucial to put them into perspective relative to statistical data.
  • Factor in personal risk tolerance, which can vary. Some may choose caution, while others trust in statistical safety.
In conclusion, giving more weight to structured and historical data is generally advisable when making safety-related decisions. It reduces the influence of emotional biases and helps in making more objective, sound choices.

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.

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.

Nursing homes You plan to sample residents of registered nursing homes in your county. You obtain a list of all 97 nursing homes in the county, and randomly select five of them. You obtain lists of residents from those five homes and interview all the residents in each home. a. Are the nursing homes clusters or strata? b. Explain why the sample chosen is not a simple random sample of the population of interest to you.

Security awareness training \(\quad\) Of 400 employees at a company, \(25 \%\) work in production, \(40 \%\) work in sales and marketing, and \(35 \%\) work in new product development. As part of a security awareness training program, the group overseeing implementation of the program will randomly choose a sample of 20 employees to begin the training; the percentages of workers from each departmer in the sample are to align with the percentages throughou the company. a. What type of sampling could be used to achieve this goal? b. Using this sampling method, determine a sample of 20 employees to be chosen.

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.)
