  • Be specific and direct in the title. Use the subtitle to give the specific context of the speech.
    -The goal should be to capture the audience’s attention which can be done with a quote, a startling statistic, or fact. It is not necessary to include this attention getter on the slide.
  • Fisher: ANOVA (analysis of variance: a collection of statistical models, used to analyze the differences among group means and their associated procedures (such as "variation" among and between groups)), Fisher’s exact test.
    Also credited with quote “correlation does not imply causation” – lifetime pipe smoker, he derided papers showing a link between smoking and cancer.
    Deming – quality control – statistical sampling
    Luhn – indexing, IR principles – use text and data to inform Business Decisions
    Tukey – exploratory data analsysis – led to S, S+ and R
    Howard Dresner – modern proponent of BI
    Tom Mitchell’s ML book – still a best-seller
    Fourth Paradigm – data driven scientific discovery – inspired by Jim Gray’s work at MSR. His primary research interests are in databases and transaction processing systems -- with particular focus on using computers to make scientists more productive. He and his group are working in the areas of astronomy, geography, hydrology, oceanography, biology, and health care.
    Other scientific discovery paradigms: empiricism, analysis and simulation
