    Materials include: web page, spreadsheet, pdf file, video of this page, local video
    * Population, Sample, Data, Statistic;
    * Discrete or Continuous;
    * Take a Samples;
    * Look at the Data;
    * Theoretical vs Experimental & Descriptive vs Analytical Statistics;
    * Probability (not really covered);
    * More Vocabulary and Topics that Are Not Included on this Page;
    * The Binomial Distribution;
    * Thank Goodness for Probability Density Functions;

  • A Guided Tour of The Spreadsheet stat.xls
    Materials include: spreadsheet, video local video
        Personally, I wouldn't write a stat test without it, and, it's the perfect tool for students to verify written homework, create their own problems, or work on a lab.
    * mean of 5, 10, 20, 30 pieces of data;
    * mean and standard deviation of three groups of 10 scores;
    * standard deviation of 10 numbers using the formula displayed in table format.
    * x-score or z-score or mean or standard deviation
    * mean, standard deviation, and z-scores, and stanine for 30 pieces of data;
    * traditional uses of z-scores and probability table;
    * probability given a normal distribution;
    * traditional & cumulative z-scores probability table;
    * P(x<a), P(x>a), P(a<x<b);
    * probability in a binomial distribution
  • A Video about the HYPOTHESIS TESTS pdf file
    Materials include: web page, pdf file, spreadsheet, video , local video,
          I wouldn't teach hypothesis testing without it. It provides the BIG PICTURE, and a superlative summary, of hypothesis testing and tests.
