· Website: Buchner, A., Faul, F., & Erdfelder, E. (n.d.) G*Power. Retrieved January 29, 2010, from http://www.gpower.hhu.de The G*Power website explains the purpose and features of G*Power and allows users to download the program. Downloading any software from a site that is not the official site of the software creator can cause issues. There are a variety of sites from which you can download G*Power, beyond the one provided in this course. These sites are safe. However, the software that is bundled with the installers can be more or less annoying, and can often introduce you to additional (harmless) software. This software should not be mistaken for viruses. In fact, if you are very careful, you can completely avoid installing any other software, but to do that, you must read carefully every screen that is presented in the installation process. In the case of G*Power, you can avoid any problems by downloading the software from the original site: http://www.gpower.hhu.de
