Summary: In this program, grumpy old men and competitive statistics students serve as samples for working with two more types of numerical representation: variability and relative standing. Section one wrestles with range, deviation, variance, and standard deviation in detail and tackles the Empirical Rule, while section two dives into Z-scores, outliers, and percentiles.

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: In the spirit of a famous rhetorical question, this program explores the world of scientific measurement at the molecular and atomic level. Host Alan Davies tries to establish the length of a piece of household string-but what appears to be a simple task soon turns into a mind-bending voyage of discovery. After discussing the matter with leading mathematician Marcus du Sautoy, Davies learns...

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...

Summary: Using examples drawn from a number of sources-including "Statisticalisimo," the game show of statistics-this program outlines the properties of a normal probability distribution and takes a look at the mean, the standard deviation, the Z-score, and the Z-score table. The properties of a uniform distribution are enumerated as well, along with how to calculate the mean and the standard deviation....

Summary: Operating on the premise that the physical world can be described by mathematical relationships, this program uses a simple yet powerful series of experiments to study a specific physical phenomenon-the motion of a steel spring. Viewers learn how to construct equations involving dependent variables, independent variables, and known constants in order to predict and measure acceleration and...

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: Maternity Glenda is expecting twins. What, then, is the expected number of female babies? After distinguishing between qualitative and quantitative random variables, this program considers the relationship between probability distributions and histograms, distribution curves, little x and big X, and expected values. Deviation, variance, and standard deviation for probability distributions are...

Summary: In this program, data derived from a bully convention helps illustrate how statisticians ensure statistical reliability. After describing reliability testing, the mean of a sampling distribution, the Central Limit Theorem, and the standard error of the mean, the focus shifts to point and interval estimators. The subject of confidence intervals-including confidence coefficients, errors of...

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: A knowledge of graphing is essential to visualizing data-and sometimes leads to free nachos. Moving beyond the relative frequency histogram, this program studies the distribution curve and the stem-and-leaf display. Then, after distinguishing between statistics and parameters, the program thoroughly investigates measures of central tendency: the mean of samples and populations, the median, and...

Summary: In this program, an evil genius named Emily and other experts reveal two more probability distributions for discrete random variables. First, the Poisson approximation to the binomial and its use in the Poisson Probability Formula are spotlighted, along with the natural logarithm constant. Then, the Urn Model is appraised, in which sampling both with and without replacement is demonstrated.

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: 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%...
