STATISTICAL ANALYSIS & DATA ANALYSIS
NCSS has specialized
in providing statistical analysis software to the
occassional user of statistics. Our current release, NCSS
2017, is comprehensive, easy to use, and runs under Windows
7/8/10/vista/XP sp2.
PASS 15 - POWER ANALYSIS AND SAMPLE SIZE
PASS
performs power analysis and calculates sample sizes. Use it
before you begin a study to calculate an appropriate sample
size (it meets the requirements of government 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.
PASS lets you solve for power, sample size, 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 results
in your proposal.
PASS is a standalone system. Although it is
integrated with NCSS, you do not have to own
NCSS to run it. You can use it with any
statistical software you want.
PASS is accurate. It has been extensively
verified using books and reference articles. Proof of the
accuracy of each procedure is included in the extensive
documentation.
PASS comes with the original 490-page manual
and a 250 upgrade manual that contain tutorials, examples,
annotated output, references, 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.
PASS Beats the Competition!
No other program calculates sample sizes and power for
as many different statistical procedures as does PASS.
Specifying your input is easy, especially with the online
help and manual.
Choose PASS. It's more comprehensive,
easier-to-use, accurate, and less expensive than any other
sample size program on the market.
