· Experiment Design and Analysis

· Software:

· Eureqa Formulize: http://formulize.nutonian.com/ (Searches for equations giving the best fit to data, while you watch!)

· On-line fitting of 2D and 3D data (You pick the equation and it finds the constants giving the best fit.)

· How to select DoE software

· Excel tutorials

· Gnumeric (free open-source substitute for Excel, for data analysis)
