Part 1 for Stats Book
All members were present during this podcast
The way we did this podcast was that we both recorded chapter by chapter having to speak on all of them by themselves then we was able to have a little discussion at the end of it to see whats ones opinions were and what we got from it at the end of the chapters. 

We read from chapters 1-4 being able to speak on those

When discussing chapters 3, 5, or 6, incorporate the following article into your discussion:

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.

The last two minutes of your podcast were solid, but it wasn't always clear that everyone read the book. If you had posted this earlier, I would have asked you to respond to the following prompts:

  1. Choose one of the quotations inside the front cover and discuss how it relates to the Introduction.
  2. Put the second paragraph on Page 18 (“A river cannot….”) into your own words.
  3. What is the advantage of a stratified random sample and what difficulties does it pose, according to chapter 1?
  4. When we see an average reported, what do we need to ask besides which kind of average is being used? Why?
  5. 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?
  6. Explain why advertisers often rely on a very small sample to substantiate their claims.
  7. What does the author mean on Page 45 when he says, “Hardly anybody is exactly normal in any way…?”
  8. How can the graph of the advertising agency’s business be misleading when the graph clearly shows such an upward trend?
