Instructions For Presentations earch Person Will Present A Chapter From

Each person will present a chapter from the book “A Mathematician Reads the Newspaper” by John Allen Paulos (see syllabus). Two copies of the book are on reserve at the reserve book desk in the library under my name for Econ 309. There is a listing that shows which day your presentation is, the chapter you are to present, and the order in which the presentations will occur. Note that the order will change some due to the fact that some students will be using PowerPoint and some will not (see note below concerning the use of PowerPoint.) The chapters are short, so the total time of the presentation will be limited to 5 minutes. You should plan your presentation so that it takes approximately 4 to 4.5 minutes, in case someone asks a question.

You should pay attention to the presentations, because there will be some True or False questions about a few of the presentations on the final exam. Grades and feedback will be available in your moodle account sometime after all the presentations for your class are finished. Some hints: Each chapter has a title and a subtitle. The title is supposed to sound like the headline from a newspaper article. These titles are only indirectly related to the point of the chapter.

Often the subtitle reveals the true point of the chapter. Your presentation should explain the point of the chapter, giving at least one example. You are encouraged to add examples that are not given in the chapter, but this is not required. If you do include an example from outside the chapter, you should say where you got it from or whether you made it up yourself. The book is old, so if possible, try to update the examples.

Trades: You must present the chapter you are assigned. However, in the spirit of free markets, you can present on a different day than what you are assigned, if you can find another student in your class who wants to trade days with you. If you are able to arrange such a trade, both students must email me separately to inform me of the trade at least one day before the first of the two students is to present. Note: You can use PowerPoint if you want, but I don’t care whether you use it (you can still get an A either way.) You can give the class a handout if you want. If you are going to use PowerPoint, have your Powerpoint show on a flashdrive (do not download it from your email.) Also be prepared to present without the Powerpoint show in case something goes wrong with the equipment (it happens.)

Paper For Above instruction

The assignment involves preparing and delivering a presentation based on a chapter from John Allen Paulos's book “A Mathematician Reads the Newspaper”. The presentation should explain the main point of the chapter, ideally supported by at least one example. The presentation must be concise, approximately 4 to 4.5 minutes long, to allow time for questions within a total limit of 5 minutes. The presentation can be supplemented with PowerPoint or handouts, but use of PowerPoint is optional, and preparation for an equipment failure is advised. Students are encouraged to trade presentation days if mutually agreed upon, with prior email notification to the instructor. The content of the presentation should include an analysis of the chapter's main message, which is often revealed by the subtitle rather than the title, and may include updating outdated examples.

Participation in this activity prepares students for future assessments, as True/False questions about the presentations will appear on the final exam. The grading and feedback will be accessible via Moodle after all presentations are completed.

Analysis and Explanation of the Chapter

In this presentation, I will discuss the key points of the assigned chapter from “A Mathematician Reads the Newspaper” by John Allen Paulos. This book explores various misconceptions about probability and statistics that are routinely encountered in the media and everyday life. Since the titles of chapters are designed to mimic newspaper headlines, they often serve as cues to the core message, which is usually clarified in the subtitle. Therefore, understanding the subtitle is crucial to grasping the chapter's main idea.

This chapter emphasizes the importance of critical thinking when interpreting statistical data. For instance, Paulos illustrates how superficial interpretations can lead to misleading conclusions. An example from the chapter involves the probability of a certain event based on reported statistics, which can be distorted by factors such as base rates or sampling biases. To make the demonstration concrete, I have devised an updated example based on recent health data: suppose a new screening test reports 99% accuracy in detecting a disease, but the disease itself has a prevalence of only 1%. Without understanding the base rate, one might falsely assume that a positive test nearly guarantees the presence of the disease. This highlights the necessity of considering prior probabilities, as Bayesian updating suggests that the probability of actually having the disease, given a positive test, is significantly lower than 99%.

Furthermore, Paulos discusses the common fallacy of confusing correlation with causation. For example, an increase in ice cream sales and the number of drowning incidents both rise in the summer, but one does not cause the other; rather, both are influenced by a third factor: hot weather. Such misconceptions foster unwarranted beliefs and poor decision-making. Recognizing these flaws in reasoning is vital in forming accurate judgments about data and discourse presented in newspapers and other media.

In conclusion, the chapter advocates for a skeptical attitude towards statistical claims and emphasizes the importance of understanding the context, background, and statistical principles behind reported data. By applying critical thinking and fostering statistical literacy, individuals can avoid being misled by superficial appearances and make better-informed decisions. To illustrate, I have included an example involving current health campaign statistics to demonstrate how statistical literacy can lead to a more nuanced understanding of health risks.

In summary, Paulos's chapter underscores that awareness of common statistical pitfalls and logical fallacies is essential in interpreting newsworthy data, ultimately fostering a more informed and rational public discourse.
