http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1613
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1613Using cooperative learning methods, this activity helps students develop a better intuitive understanding of what is meant by variability in statistics. Emphasis is placed on the standard deviation as a measure of variability. This lesson also helps students to discover that the standard deviation is a measure of the density of values about the mean of a distribution. As such, students become more aware of how clusters, gaps, and extreme values affect the standard deviation.Mon, 16 Oct 2006 10:48:16 -0400Body Measures: Exploring Distributions and Graphs Using Cooperative Learning
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1612
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1612Using cooperative learning methods, this lesson introduces distributions for univariate data, emphasizing how distributions help us visualize central tendencies and variability. Students collect real data on head circumference and hand span, then describe the distributions in terms of shape, center, and spread. The lesson moves from informal to more technically appropriate descriptions of distributions. Mon, 16 Oct 2006 10:45:49 -0400Presenting Data

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1036
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1036This applet is designed to teach students how bin widths (or the number of bins) affect a histogram. A histogram of the time between Old Faithful eruptions is shown. Students can change the bin width by dragging the arrow underneath the bin width scale. The changes are observed in the structure of the histogram. An article and an alternate source for this applet can be found at http://www.amstat.org/publications/jse/v6n3/applets/histogram.html.Wed, 22 Jun 2005 03:07:17 -0400Histogram Applet
