NOTE from JH: When the new series was posted, the 26 programs in the ORIGINAL SERIES appeared as numbers #33-58, But, as the NOTICE describes, they have since been removed. JH still has the 'original 26', both in VHS and (newer!) formats -- contact him if interested in viewing them.

KEY WORDS: Teaching, Multimedia, Visual aids.


Against All Odds: Inside Statistics is a collection of twenty-six half hour outstanding video presentations that depict how statistics is used in society. This outstanding series was produced under the guidance of Dr. David Moore of Purdue University. The tapes are available from The Annenberg/CPB Collection, and are also offered free to schools that adopt certain text books. Using short excepts from the thirteen hours of video in the classroom can be a excellent way introduce students of statistics to real problems. Contained in this paper is a detailed listing of the real world setting, the specific statistical items discussed, and a time index so that instructors can go directly to a desired story on a tape. As an example of how to use a tape in class, consider showing students the data and graphs that were used by engineers to determine if temperature was related to joint scaring for a particular complicated machine. Then show a video of the result of what happened when all the data were not considered: the space shuttle Challenger exploding! The impact on the class can be quite dramatic.

Those segments of the series that I think can be used effectively in a classroom setting are highlighted. A H to H H H H rating is used. These are my ratings; yours will vary. The portions of the tapes in which Teresa Amabile, series hostess from Brandis University, teaches are generally not rated, since she is playing the role of the instructor, the task you will be performing in the classroom. Statistical terms are shown in bold type. The names of the experts used in the stories are given.

A VCR and a TV monitor are all that is needed. Knowing where specific segments start and end is greatly enhanced if your VCR has a "real time" counter as opposed to one that counts revolutions of the videocassette reel. Each tape in the series contains two 30 minute programs. All times in this paper are measured from the front of a tape, beginning at the first video signal on the tape. This signal is always "1-800-LEARNER", the phone number for information on the tape series. When this first appears, reset your VCR counter to "0:00". The time corresponding to "END OF PROGRAM" indicates the point at which the program credits start. Times on the left indicate the time index at which a segment starts; the times given in brackets show the elapsed time for that particular segment. Note, because of differences in the productions runs made for duplicating this series, the "gap time" between the two programs on each tape may vary.
Your tapes may have different gap times than mine; if so, note the difference and adjust all times on the even numbered programs accordingly.

I am not advocating showing any tape in its entirety as a substitute for live instruction. Because we feel that the tapes are valuable, we indicate on our course syllabi which programs correspond to the lectures. We then make all the tapes in the series available to our students in our video viewing center for "after hours viewing". Although we encourage students to watch the tapes, most do not.

Enjoy the series!
