  • Statistics and Scientific Decisions

    1. Textbook: Darrell Huff: How to Lie with Statistics

    2. Statistical techniques

      1. Asking good questions and appropriate context

      1. Selection of "useful" data
      2. Presentation of results
      3. Simpson's paradox
        1. How can differing statistical results all be correct (or all wrong)?
        2. SPURIOUS CORRELATION AND IT'S DETECTION
        3. SPURIOUS CORRELATION AND IT'S DETECTION (change the "spurXX" number in the URL box)

    4. Analysis of small statistical effects

      1. Supra-linear theory (John Gofman)

    5. Types of studies

      1. Epidemiological study
        1. Correlates various events or phenomena
        2. Does not deal with causality
      2. Causal study
        1. Involves determination of cause and effect, not just correlation
        2. Should include study of physical mechanism of problem
        3. Hidden or "lurking" variables
      3. Loss of life expectancy summaries
        1. Loss of Life Expectancy (LLE) tables
        2. Loss of life expectancy charts for various situations
      4. Cost to value analysis
        1. Placing a "monetary" value on lives?
        2. Cost per life saved tables
        3. Competing lifesaving goals

    6. Examples

      1. Inoculation data
      2. Low levels of carcinogens or poisons (general)
      3. Low-frequency electromagnetic radiation
      4. Radon gas
      5. Arsenic in drinking water
      6. Second-hand smoke
      7. Saccharin
