 One-Way ANOVA This applet demonstrates the partitioning of sums of squares in analysis of variance (ANOVA). It includes some sample values and allows the user to make adjustments, which then shows the new values in the ANOVA table. Also contains an exercise set. Overall, this is a nice resource for any mathematics classroom. http://www.ruf.rice.edu/~lane/stat_sim/one_way/index.html
 Statistical Applets: Two Variable Statistical Calculator Created by Duckworth, McCabe, Moore and Sclove for W.H. Freeman and Co., this applet calculates correlation and regression information and displays graphs for a number of data sets from the text "Practice of Business Statistics." Users can also enter their own data. Even though brief, this interactive resource is still valuable for an introductory statistics course. http://bcs.whfreeman.com/tps4e/#628644__666371__
