Very cheap software (you pay for a three year licence) and very easy to use, as it is based on a spreadsheet. Indeed, it is possible to copy and paste data between Excel and StatsDirect. Also, for those who are not well-versed in statistics, there is an inexpensive book by Cole Davis called Statistical Testing in Practice, which teaches basic statistics (and some more complex stuff as well), using StatsDirect: www.coledavis.org/book.html
