I have used several statistics tools, but NCSS is the best statistics tool. It is easy to use because the interface and menu are easy to be used. And NCSS is very useful to support an analysis [in] data research.
"I really love this version of NCSS and as teacher and researcher in a medical field I can say there aren't many things I miss in it... The help system is another strong feature; the transformations interface is one of my favorites as well."
