Program 9: Correlation (30 min.) With this program, students will learn to derive and interpret the correlation coefficient using the relationship between a baseball players salary and his home run statistics. Then they will discover how to use the square of the correlation coefficient to measure the strength and direction of a relationship between two variables. A study comparing identical twins raised together and apart illustrates the concept of correlation.

Assessment does not compete for valuable teaching time; it is teaching time. This workshop shows how embedding assessment into everyday curriculum turns performance tasks into learning activities. Well-designed assessment allows teachers to shape subsequent instruction according to what their students have and have not understood. Content Guide: Monica Neagoy

Program 7: Models For Growth: Topics of this program include linear growth, least squares, exponential growth, and straightening an exponential growth curve by logic. A study of growth problems in children serves to illustrate the use of the logarithm function to transform an exponential pattern into a line. The program also discusses growth in world oil production over time. Program 8: Describing Realtionships (30 min.) Segments describe how to use a scatterplot to display relationships between variables.

Understanding is more than simply knowing. This workshop sets the stage for the entire series by examining what it means to understand, and explores how teachers can design a set of performance tasks to fairly and accurately assess the levels of understanding that their students have or have not achieved

One measure of students' depth of understanding is the connections they can make across disciplines. This workshop explores how teachers can encourage these connections by designing performance tasks that build on other disciplines

Program 25: Inference for Relationships: With this program, students will understand inference for simple linear regression, emphasizing slope, and prediction. This unit presents the two most important kinds of inference: inference about the slope of the population line and prediction of the response for a given x. Although the formulas are more complicated, the ideas are similar to t procedures for the mean of a population. Program 26: Case Study: This program presents a detailed case study of statistics at work.

Program 23 - Inference for Proportions: This program marks a transition in the series: from a focus on inference about the mean of a population to exploring inferences about a different kind of parameter, the proportion or percent of a population that has a certain characteristic. Students will observe the use of confidence intervals and tests for comparing proportions applied in government estimates of unemployment rates. Program 24: Inference for Two-Way Tables: A two-way table of counts displays the relationship between two ways of classifying people or things.

Contains two 30-minute programs. Program 1: What is Statistics: Using historical anecdotes and contemporary applications, this introduction to the series explores the vital links between statistics and our everyday world. The program also covers the evolution of the discipline. Program 2: Picturing Distributions: With this program, students will see how key characteristics in the distribution of a histogram shape, center, and spread help professionals make decisions in such diverse fields as meteorology, television programming, health care, and air traffic control.

This inspirational and intriguing program shows top practioners of science, mathematics and magic exhibiting the many ways that mathematics plays into puzzles, magic, logic, philosophy and science. A motivational tool for the classroom, with many thought-provoking conundrums and exposures of various tricks and illusions
