Statistics Calculator
Statistical
Analysis Tests At Your Fingertips
|
If you need statistical
analysis, then an essential program in
your toolbox is the Statistics
Calculator. Using a
fill-in-the-form interface, you can
quickly and easily perform significance
tests on summary data.
With
most statistical analysis software, you
have to have the raw data. You need the
entire data set in order to run even a
simple statistical test. The Statistics
Calculator is different.
It let's you perform significance tests
from summary data: counts, percents, or
means.
The
main menu of the Statistics
Calculator makes it easy
to select the right test.
If you
already have the means or percents, then
use the Statistics
Calculator to quickly get
the answers. You can make comparisons on the fly and
include them in your report. Just fill in
the form and click then Calculate button.
Here's an example of a fill-in-the
form screen to test for a significant
difference between two percents:
If it looks
easy...that's because it is. Anyone can
use the software. You don't have to be a
statistician or rocket scientist. The Statistics
Calculator is an indispensable tool for
anyone working with business or social
science data.
Plus there's extensive
online help with an abundance of examples
to answer all your questions. Here's
what's in the Statistics
Calculator with links to the online help.
