View Resource 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.

View Resource 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 "€œPractice of Business Statistics."€ Users can also enter their own data. Even though brief, this interactive resource is still valuable for an introductory statistics course.

View Resource Curve Fitting

Created by John Michel for the Connected Curriculum Project, the purpose of this module is to extend the concept of fitting a least squares line to allow fitting more complex functions, including those in which the model parameters do not appear linearly. This is part of a larger collection of learning modules hosted by Duke University.

View Resource Least Squares

Created by David Smith for the Connected Curriculum Project, the purpose of this module is to develop the concept of fitting a least squares line from the concept of orthogonal projection of a vector on a subspace. This is part of a larger collection of modules hosted by Duke University.

View Resource Least Squares

This applet allows students to manipulate a regression line to obtain the least squares regression line. The square distance from each point to the line and the sum of squares is shown by different colored squares. This site provides additional links to items such as a gallery of additional resources and also a vocabulary for students to learn the grammar of the discipline. This is a nice...
