This applet, created by David M. Lane of Rice's Virtual Lab in Statistics, illustrates many features of a two-factor analysis of variance. Allows the user to adjust the group size and group means. Gives output of ANOVA table and a Venn diagram showing how the sum of squares total is divided among SS more
This is a downloadable software simulation of light emitting diode simulation. It demonstrates band gap theory and shows how a single photon is created. Users can adjust the input voltage to allow the recombination of the electrons and holes. Note what happens to the photon when you adjust the band more
This simulation-based laboratory activity allows the student to practice several types of graphs and explore the types of information that we can collect from graphs. Coverage include exploration of linear, non-linear and logarithmic relationships as well as an error analysis.
In this applet, a mass is released at the top of a hill with a spring at the bottom. The user can drag the slider to change the angle of the hill and watch how the velocity and acceleration changes.
This National Taiwan Normal University applet enables the user to vary the angle of a corner mirror and investigate the location of the multiple images. In addition, the user can see the reflections of numerous light rays and how their backward extensions meet at the image.
This page, created by Thomas Kirkman of the College of Saint Benedict/St. John's College, introduces contingency tables with an example on fruit trees and fire blight. Two calculators are provided that allow users to enter their own contingency table and test for treatment effects. The first calcula more
This article, created by faculty members of both San Jose State University and the South Dakota School of Mines, presents a dataset containing physical measurements for 507 physically active individuals. These data can be used to demonstrate simple descriptive statistics, least squares and multiple more
