I liked how it was able to be used in any program without having to go through all sorts of other programs just to do simple statistical tasks like gauging error or sample sizes.
The interface could use some work but there are plenty of tutorials out there if you need help setting up things properly. If your looking for an excellent tool that will allow you to easily manage data from many different sources this is perfect! It has allowed me to quickly gather information about my research studies which helps keep track of what needs doing next.
