8 Fifteen-Minute Programs
Grade(s):  10 - 12
Curriculum Area:  Mathematics

The programs are arranged in logical order and progress from the simple to the more complex. The series is designed for modular use, but individual programs may be used wherever the curriculum calls for materials from statistics. Programs transports students out of the classroom to see statistics in a variety of settings and uses animated graphics to teach abstract concepts.

Teacher Guide:  The guide contains a summary of the video, student activities, background information for the teacher, and examples of applying the concepts to real-life activities.

Part II

1. Normal Curves  (14:50)
   Program opens with the question of comparing batting averages of baseball players of different eras, After a brief outline of the statistical content of the video , a histogram of the distribution of salaries in a large company appears. This density curve is used to discuss normal curveg. other examples are given.

2. Normal Calculations    (14:50)
   Using General Motors testing grounds as an example . The mean and standard deviation are calculated to see how the prototype car compares to the general population. Program shows how measurements are standardized for comparisons and projections.

3. Straight-Line Growth   (14:45)
   Human growth is used as an example to discuss linear growth by using the growth rate of Sarah against time.

4. Exponential Growth  (14:05)
   Program compares linear growth to exponential growth and uses the Gypsy Moth invasion as an example of exponential growth through he use of charts illustrating the number of offspring possible from one initial pair.

5. Scatter Plots     (14:50)
   The number of Manatees killed by power boats in Florida is used as an example to introduce and explain quantitative, explanatory, and response variables. A scatter plot is used to show the relationships between the two variables.

6. Fitting Lines to Data   (14:50)
   The programs uses weight loss to explain how data can be manipulated to formulate a straight line from which projections can be made based on one variable.

7. Correlation   (14:50)
   Twins are used to illustrate the strength of a relationship between two variables or the correlation of those variables.

8. Save the Bay  (14:00)
   This program is a "summary" of the preceding programs and shows how the various concepts discussed in other programs are actually used to track the environmental condition of the Chesapeake Bay.
