This web site offers free resources for students and researchers working with statistics
in the social sciences. All the calculators and tools featured here have been designed
with ease of use and clarity of presentation being of paramount concern. Certainly,
you should find them much less cumbersome - and definitely less expensive - than
SPSS and the like.
The output of our calculators and tools has been audited for accuracy against the
output produced by a number of established statistics packages, including SPSS and
Minitab, so you can be confident that you're not being led astray by using our
resources. However, we do need to include the standard disclaimer that we cannot
guarantee the accuracy of the results generated here.
If you find the resources on this site useful, please consider recommending us!
