Next Airing: Fri, Jan 18th, 2019 at 11:00 AM on UEN-TV

Availability information for this program

Against All Odds places a strong emphasis on "doing" statistics. Each unit is based on a video module that introduces a statistical topic in real-world context and takes you on location to where people from all walks of life are using statistics in their work. Starting with descriptive statistics, the course continues through probability and inference. Examples range from finding patterns in lightning strikes, to examining possible generic resistance to deadly Lassa fever in West Africa, to linking DDT to the decline of peregrine falcons.

Episodes:

  • What Is Statistics?

    "What's Statistics" provides an introduction to basic terms and methodin statistics and statistical analysis by examining their application in a variety of business, scientific, and academic settings. Terms an d concepts such as sampling, experimental methodology and prob- ability theory are explained through their use by companies like Domino's Pizza, in developing, evaluating and marketing new food products, and byscientists like Raul Lopez, who explains how statis- tics are an impo rtant part of his studies on weather patterns.

  • Picturing Distributions

    This program explains how graphical representations can aid the display and analysis of statistical data. Graphics such as histograms and stemplots are used to explain the center, spread and shape of distributions of data. The application of these methods by a TV station and a health care facility is explored in depth.

  • Describing Distributions: Numerical Description Of

    This program focuses on how measures of central tendency (mean. median) and dispersion (interquartile range, standard deviation) can be used to describe, explain and understand distributions of statistical data. The application of these measures to problems involving wage descrimination and the caloric measurements of foods is examined in depth. The use of graphics to explain and analyze measures of central tenden cy and dispersion is emphasized throughout the program.

  • Normal Distributions

    This program describes how characteristics of the normal distribution aid in the interpretation of statistical data. Statistical measures from previous programs, such as mean and standard deviation, are discussed in terms of their relationship to the normal distribution. These concepts are applied to demographic changes in the age of the U. S. population, and the effects those changes have on the supply and demand for social services and labor.

  • Normal Calculations

    This program focuses on three statistical measures or techniques: 1) zscores; 20 Quantile Plots; 3) Relative frequencies. These 3 measures or techniques for analyzing data are applied to distributions involvi ng cholesterol levels and clothing sizes. The measures are shown to be effective in locating where individual cases fall within normal distributions.

  • Models for Growth

    This program examines the two most common patters of growth that statistics often reveal: exponential growth and linear growth. The program uses examples such as the growth of children and increase in gypsy moth populations to explain that linear growth is additive while exponential growth is multiplicative.

    This program describes how relationships between numerical variables can be understood using statistical and graphic techniques. Scatterplots and regression lines are utilized as methods which are capable of showing the underlying patters of complex sets of data. Research studies about the endangerment of Florida's manatees (sea cows) and human obesity are utilized as examples to display how scatterplots and regression lines aid interpretation and analysis.

    Statistical correlations, as a measure of linear relationships, are the subject of this program. Using examples such as the relationship between major league baseball salaries and home run production. The programexplores how statistical correlations can explain the strength and direction of the linear relationship between two variables. The program uses both statistical and graphic techniques to explain correlation relationships.

  • The Question of Causation

    When are statistical associations proof of causal relationships? This issue is explored in this program using the Surgeon General's report on smoking and health as an example of an extensive study which utilized statistical assocations to come to the conclusion that cigarette smoking is related to cancer and other diseases. The program specifies the criteria that must be met before causation can be infered from statistical association.

  • Significance Tests

    Significance tests are important statistical tools because they revealwhether a given statistic is a result of random variation or evidence of a meaningful relationship between variables. This program examines the application of significance tests by utilizing research on Shakes peares's texts and racial discrimination in the Federal Bureau of Investigation. In both cases, significance tests are used to test the validity of research hypotheses.

  • Comparing Two Means

    This program applies T-procedures to situations in which comparisons must be made between the mean scores of two groups. This procedure is extremely important in determining whether the perceived difference between groups is statistically significant or the result of random variation. The program shows how T-procedures can be used to determine whether the increase in earnings of persons participating in a job training program are statistically different from persons who did not participate in the project.

  • Inference for Proportions

    This episode explores the use of the standard deviation in determiningthe significance of data. Formulae are given for examining whether di screpancies in data are due to chance or not. In addition to the formulae, independent cases are examined for examples of ways in which suchstudies have come into play in actual circumstances, including the Sa lem witch trials and toxic waste in Massachussetts.

  • Inference for Two-Way Tables

    Inference for Two-Way Tables focuses on statistical techniques for judging the relationships between categorical variables. The program utilizes the chi-square statistic to explain how analysts determine whether the observed differences between groups are statistically significant or the product of chance or random variation. By using this technique the program highlights a studyu which found that older women were less likely to receive treatment for serious medical disorders than younger women.

  • Case Study

    This final episode deals with the very current issue of AIDS, and a very major role that statistics has played in the treatment of that disease. We follow the drug AZT through its invention by the Burroughs-Wellcome Company, through a test run by that company, to its final approval by the Food and Drug Administration as an effective combatant to the AIDS virus. The emphasis is on how statistical analysis was able to determine the effectiveness and reliablility of that drug.
