meets the requirements of govement agencies
that demand technical justification of the
sample size you have used). Use it after a
study to determine if your sample size was
large enough.

effect size, and alpha level. It automatically
displays charts and graphs along with numeric
tables and text summaries in a portable format
that is cut and paste compatible with all word
processors so you can easily include the

integrated with NCSS, you do not have to own
NCSS to run it. You can use it with any
statistical software you want.

formulas, verification, and complete instructions
on each procedure. And, if you cannot find an
answer in the manual, our free technical
support staff (which includes a PhD
statistician) are available.
