Summary: This program demonstrates how "qualitative" bivariate data can be visualized by using a modification of the simple Bar Chart. Quantitative data is dealt with by developing the Dot Plot into the Scatter Diagram, which allows any correlation to show itself in a linear relation. The program explains how this correlation can be modeled by calculating a "Line of Best Fit," how to calculate 95%...

Summary: In this program, a helpful bunch of bullies comes to grips with and alternate hypotheses, the significance level, the test statistic, acceptance and rejection regions, one- and two-tailed tests, and Type I and Type II errors. The essentials of dealing with small samples-including t-distribution, the t-Value Formula, and degrees of freedom-are also tackled.

Summary: What are the odds that a casino card dealer and a pair of Simon and Garfunkel wannabes know something about probability? This program begins by defining probability and sampling, experiments, simple and compound events, and sample space. Next, the formula for finding probability is analyzed, along with the composition of simple and compound events, mutually exclusive events, and complements of...

Summary: Beginning with an explanation of the difference between "qualitative" and "quantitative" data, this program goes on to explain various ways of presenting data, including Dot Plots, Bar Charts, and Histograms. The program also explains Summary Measures, Characteristic Values, and how to arrive at the Mode, Median, and Mean, with a discussion of their individual drawbacks and advantages. The...

Summary: In this historical reenactment, Florence Nightingale uses applied statistics to disprove the medical assumptions of her day. Using fatality counts from the Crimean War, Nightingale develops a progressive series of statistical diagrams that reveal startling information: most soldiers did not die of their wounds, as reported, but in army hospitals, from diseases related to poor hygiene. When...

Summary: This program examines the measurement of blood pressure to introduce the idea that multiple measurements may produce very variable results. The idea that measurement "errors," together with fluctuations in the parameters being measured, create variability is followed by an explanation of both Systematic and Random Error and the recognition of the need for statistical techniques to handle this...

Summary: This program begins with an explanation of the difference between a Population and a Sample, and the reasons why samples are so important in estimating data relating to populations too large or too impractical to be measured in their entirety. The program emphasizes the need for random samples, explains how several random samples of the same size will vary, and then looks at ways of dealing...

Summary: After concisely defining the purpose of statistics, section one of this program uses Five-Card Charlie's Fuzzy Dice Cola to examine the concepts of population and sampling and to catalogue the elements of statistical problems. In section two, data derived from the National Martyr Competition provides an opportunity to set up a relative frequency histogram, which involves classes and their...
