I love StatCrunch and have used it for years. My Statistical Methods online class used it for the past two semesters to make graphs of all types and do regression analysis. They were all able to make, copy, and use the output from StatCrunch. It is very easy to learn and use and well worth the subscription price. I also use StatCrunch for my own statistical analysis and to make graphics for teaching at all levels of Statistics.
Easy to use, versatile, accurate. The online storage space for data sets is generous and the new abilities to share data sets and reports with other users is a great feature.
