Using Samples [electronic resource]

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 with this variability, calculating the Standard Error of the Mean, and how to estimate the "95% Confidence Interval. The program goes on to show how, when dealing with quantitative data, you can calculate the size of the sample that is needed in order to achieve the precision required.

A Gift for Math [electronic resource]

Endowed with an elementary representation mechanism, the human brain is naturally predisposed toward mathematics. This program seeks to understand the biological basis of humankind's "gift for math"-and why, beyond that baseline computational ability, some people are capable of scaling the highest peaks of mathematical comprehension. Experiments with animals, studies of very young children, cases involving patients with brain injuries, and analysis of brain imaging data are included.

Probability [electronic resource]

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 events. Finally, dependent and independent conditional events are discussed.

Reading a Ruler [electronic resource]: English and Metric Measurements

In the first lesson, the different forms of English measurement are discussed and displayed as they would appear on a ruler. The viewer also learns how to understand fractions when measuring and how to find exact measurements using a ruler. The second lesson deals with the metric system by introducing the meter and other metric measurements. Viewers learn how to read a meter stick, and common abbreviations of metric measurements are discussed. Viewers also learn how to convert measurements using the decimal point.

Measurement [electronic resource]: Long and Short of It

Emphasizing hands-on practice, this program is an excellent tool for introducing the basics of linear measurement: its history, terminology, systems, and practical applications. Using both customary and metric rulers, Measurement: The Long and the Short of It will guide your students through the process of taking measurements, performing related calculations using whole numbers and fractions, and arriving at answers they can feel confident with. By the time the program is over, students will understand exactly what measurement is-and why it's relevant to their lives. Includes a workbook. Correlates to all applicable state and national standards.Recommended for middle school, high school, and vocational/technical school.

Mathematics and Nature [electronic resource]

The shapes of natural things-trees and clouds, blades of grass and galaxies-seem countless. Closer observation shows that nature only presents a small number of fundamental shapes and that these basic shapes obey strict laws. This program explains a new science of natural forms that aims to understand the order of nature. We see that most natural phenomena, whether the movement of planets or the secretion of hormones, follow regular cycles. Attempts to describe the order of nature mathematically have led to a new geometry: fractal geometry.

Handling Variability [electronic resource]

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 variability in order to allow inferences to be drawn and decisions made.

Describing Data [electronic resource]

Beginning with an explanation of the difference between "qualitative" and "quantitative" data, this program goes on to explain various ways of presenting data, including Dot Plots, Bar Charts, and Histograms. The program also explains Summary Measures, Characteristic Values, and how to arrive at the Mode, Median, and Mean, with a discussion of their individual drawbacks and advantages. The program goes on to discuss handling the Spread of Distribution, and explains techniques for measuring Spread, including Quartiles, Inter-quartile Range, and Standard Deviation, and concludes with modeling using Normal Distribution.

Bivariate Data [electronic resource]: When y Depends on X

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% Confidence Bands, and how to calculate a summary measure for any correlation called the Correlation Coefficient. Finally, the program explains how to deal with data that indicates a curved Line of Best Fit by either finding a way of re-plotting to provide a linear correlation or, alternatively, how to calculate a curved Line of Best Fit.

Graphs [electronic resource]

This video describes how to read, interpret, and evaluate data displayed in bar graphs, line graphs, and pie charts. Dramatized segments and computer animations illustrate ways to determine the financial advantages of a staggered breeding schedule at a dairy farm; allocate rack space in a CD store, based on regional and local sales figures; and decide whether an athlete's physical characteristics indicate competition as a sprinter or as a distance runner.

Decimals and Exponents [electronic resource]

This video describes how whole numbers and decimals are used in the monetary system, how to calculate costs in foreign currencies, and how to use exponents. Dramatized segments and computer animations focus on ways to determine the international value of U.S. dollars at a currency exchange; select chairs for an interior decorating job while staying within a budget; and calculate interstellar distances using scientific notation-and imagination.
