Subject: Mathematics (7 - 12)
Title: Statistically Thinking
Description: The object of this project is for students to learn how to find univariate and bivariate statistics for sets of data. Also, the students will be able to determine if two sets of data are linearly correlated and to what degree. The students will use Microsoft PowerPoint and Excel to find, organize, and present their projects to the class.

Subject: Mathematics (9 - 12), or Technology Education (9 - 12)
Title: Ballistic Statistics!
Description: Students will collect examples of various statistical instruments and form an electronic scrapbook. These materials will be gathered from electronic sources in addition to periodicals and other print resources.

Title: How Old Are the Stars?      Add Bookmark
Description: In this Science NetLinks lesson, students determine the age of a star cluster by observing, measuring, and plotting astronomical data. They examine the Jewelbox cluster, located within the southern constellation Crux, and determine its age using a relationship between temperature, color, and luminosity. Before beginning this lesson, students should understand the life cycle and composition of stars. Students should also understand the relationship between temperature and color.

Title: State Names      Add Bookmark
Description: In this Illuminations lesson, students use multiple representations to analyze the frequency of letters that occur in the names of all 50 states. In the process, they learn how various representations, including steam-and-leaf plots, box-and-whisker plots, and histograms, can be used to organize the data.

Title: Sticks and Stones      Add Bookmark
Description: In this Illuminations lesson, students play Sticks and Stones, a game based on the Apache game Throw Sticks, which was played at multi-nation celebrations. Students collect data, investigate the likelihood of various moves, and use basic ideas of expected value to determine the average number of turns needed to win a game.

Title: The Effects of Outliers      Add Bookmark
Description: This lesson, one of a multi-part unit from Illuminations, provides students with the opportunity to investigate the relationship between a set of data points and a curve used to fit the data points, using a computer-based interactive tool. Using the Regression Line Applet, students investigate the effect of outliers on a regression line and easily see their significance.
