In this podcast, we talked about chapters 1, 2, 3 and 4. We recorded together as a group and went around in a circle type of discussion, but that did not worked out. We had to record and post this first podcast as soon as we could to receive feedbacks. In our next podcast, we will record together.
Also, each member of your group should find an article online containing a misleading graph and discuss it during the podcast (be sure to talk about why it’s misleading!). Be sure to include a link to all articles in the text of your post of the podcast that corresponds to chapters 3, 5, or 6.
I’m happy to hear everyone had something to contribute, but it wasn’t really a discussion; it sounded like your group members split sections of the book to summarize and weren’t really listening to one another. Sometimes the speaker gets cut off. Why no discussion of the introduction? For next time, please respond to the following questions:
Choose one of the quotations inside the front cover and discuss how it relates to the Introduction.
Put the second paragraph on Page 18 (“A river cannot….”) into your own words.
What is the advantage of a stratified random sample and what difficulties does it pose, according to chapter 1?
When we see an average reported, what do we need to ask besides which kind of average is being used? Why?
Which kind of “average” (statisticians call all three “measures of central tendency”) would give me the best way to compare the performance of two classes of a required math course? Why?
Explain why advertisers often rely on a very small sample to substantiate their claims.
What does the author mean on Page 45 when he says, “Hardly anybody is exactly normal in any way…?”
How can the graph of the advertising agency’s business be misleading when the graph clearly shows such an upward trend?
