The Geometer’s Sketchpad – Least Squares

animations, chemometrics, chemometrics, Resources by Format, statistics using applets, Techniques

This site provides a java-based demonstration of how a least-squares analysis works. The applet opens with a set of data points with a superimposed line. By clicking and dragging, the user can move the data points and change the slope and/or the y-intercept of the line. The residual error for each data point is shown as…

Rice virtual lab in statistics

animations, chemometrics, chemometrics, etexts/tutorials, exercises and problems, general, Resources by Format, statistics using applets, Teaching Resources, Techniques, virtual labs

This site is devoted to statistical tests and demonstrations of their use and was created with the support of the National Science Foundation. One section is a complete reference guide - the online statistics textbook, with detailed descriptions of all things statistical. The second, and most fun section, is simulations/demonstrations section where nearly twenty statistical tests…

Applets for Chromatography, Signal Processing and General Analytical Chemistry

animations, Applications, chemometrics, chemometrics, electrochemistry, equilibrium, instrumentation, interactive software and applets, quantitative analysis, Resources by Format, separations, spectroscopy, statistics using applets, Techniques, tutorials

This site offers Java-based applets as organized in 4 categories: analytical and general chemistry, instrumental chemical analysis, instrumentation/signal processing, data analysis/chemometrics. Each applet includes a short introduction followed by a user controlled input of experimental conditions, such as seen for diffusion in electrochemistry.The website is available here .

Uncertainty Calculator

chemometrics, statistics using applets, Techniques

This site contains a JavaScript "Uncertainty calculator," which determines the uncertainty of a calculated result given the uncertainties for the measurements. The website includes background material on calculating uncertainties and instructions for using the calculator. The software also is available as a free download. The website is available here .

The Probability Pipe Organ

chemometrics, Resources by Format, statistics using applets, Techniques

This site provides a Java-based simulation that uses a random number generator to demonstrate the principles of probability. The website is available here .

DynaFit – (Bio)Chemical Kinetics and Equilibria

Applications, bioanalytical, chemometrics, protein analysis and binding, statistics using applets, Techniques

The freely available software package uses a nonlinear least-squares regression analysis to fit chemical kinetic, enzyme kinetic, or ligand-receptor binding data to a user-defined molecular mechanism represented symbolically by a set of chemical equations. Dynafit is available for Microsoft Windows XP or 2000. The website is available here .
