Software, Free
The Internet offers a large and growing number of free computer programs of good quality that can be used in the planning, performance, and analysis of research studies. These applications can meet many, most, or all the needs of most researchers. Some programs can be downloaded and run on one's own computer, and some are online programs (i.e., interactive statistical calculating pages on the Internet). Some of these interactive pages are also downloadable. Most of the downloadable programs are suitable for personal computers (PCs), and some are made for Apple-based Macintoshes (Macs).
