Day 3 in SCI110: Science, PseudoScience, and More Statistics

Spring 2005 Schedule
Last time: Statistics
- On-line Statistical Stuff (Mean and Variation) -- have you done it?
- Statistical Definitions and Formulas (Page 5, worksheet)
- Population sampling (use your data sheet)
- Arm length measurements, and statistics by hand
- Using SPSS
- pulse rate exercise ("paired information")
Today:
- Scientist Homework presentations
- Science versus PseudoScience -- knockdown!
- Assignment of homework topic (p. 16)
- SEM exercise (sorry: more statistics!;)
  - Sampling Error:
    "An error which arises because the data are collected from a part, rather than the whole of the population. It is usually measurable from the sample data in the case of probability sampling."
  - sampling and resampling exercise
    - Standard Error of the Mean
    - Histograms
    - Random samples
Homework:
- Investigation of Dietary Supplement (due next class period!)
  - Use this page from your workbook (Evaluation of a claim) as a model of things to discuss.
  - Use the headings from your worksheet's questions (Investigation of Dietary Supplement) to organize your paper.
  - If you need to go to two pages, that's fine. Shouldn't require more than two, however: this is a summary.
  - Don't forget the references!
