Announcements:
- The final is Monday, December 7, from 8:00 to 10:00.
  Our final exam will be split into two parts: short presentations of our reports (first hour), followed by the written exam (one hour of mathematics).
  You should be preparing a 6-minute presentation.
- Your z-calculations, given the proportions in the BCC report, are returned. Four of you didn't do them. I hope that you'll be able to do these calculations for the exam.
  Emily had a really neat idea, which I should have thought of (and which we should check out).
- Today I'll turn it over to you, to ask any questions you may have about the details you'll need as you write up your reports.
  Make sure that you review your first exam, and can do those problems.
Know about and/or how to use or do the following:
- Pascal's triangle
- Graphs
  - Simple Graphs (e.g. Facebook)
  - Weighted graphs (e.g. The Enemy of my Enemy)
  - PageRank (e.g. Google)
- Adjacency matrices
- Moran's I -- given the formula, how to calculate
- weighted averages -- how to calculate
- how to digitize coordinates -- need for an origin, need for a reference point.
- turning a lead soil depth core into a lead value with the GraceSandra method
- Understand the soil lead profile, and how the model can be used (e.g. for a solution to the lead problems by homogenizing soil).
- We also used the soil lead profile to obtain surface estimates for the foundry site.
- Turning USAToday lead values into a single estimate for a location as a weighted average.
- know the difference between a normal distribution and a long-tailed, non-normal distribution (and how a normal distribution is related to Pascal's triangle).
- Compute a z-score for the proportions of the Newport study.
- Know how to interpret a z-score for the proportions of the Newport study.
- Understand confidence intervals, as presented in the report of the BCC.
- You should be able to interpret the graphs we have developed for the lead study, or the statistics for the well-being study.
