Abstract

One option for Extension professionals wishing to use free statistical software is to use online calculators, which are useful for common, simple analyses. A second option is to use a free computing environment capable of performing statistical analyses, like R-project. R-project is free, cross-platform, powerful, and respected, but may be difficult for beginners to learn. Using a graphical user interface allows new users to perform common analyses using pull-down menus and dialog boxes without programming knowledge. An example of an R-project program, performing a linear regression and producing relevant plots and statistics, is included.
