Why choose InStat?

Most statistics programs are designed by statisticians, for statisticians. These programs are feature-packed and powerful, but can overwhelm scientists with thick manuals, obscure statistical jargon and high prices. GraphPad InStat is different. InStat is designed by a scientist for scientists.

As reviewed in Science magazine:
"InStat takes a kinder, gentler approach...All prompts to the user are in plain English and simple to follow. The program guides the user through a four-step process; defining the data type, entering data, choosing a statistical test, and presenting the results...The user navigates easily through these steps, to lucid and complete output...The analysis checklists are a masterstroke...This small, but effective package is highly recommended."
–John Wass, Statistics, Fast and Easy, Science 282:1652, Nov 27, 1998.

Five reasons why you should choose InStat:
InStat guides you step by step
InStat conquers the learning curve by escorting you through statistical analyses. You'll master the program in just a few minutes – really.

Clear analysis choices with explanations
You don't have to know the name of the test you need. InStat helps you pick an appropriate test by asking questions about your data. If you are unsure, consult the extensive help screens, which explain the statistical reasoning in plain language.

Easy to understand results
InStat does not assume that you are a statistics whiz. It presents results in simple paragraphs, with a minimum of statistical jargon. InStat's help screens review the use of each test and explain every portion of the results.

Unique analysis checklists
With other statistics software, it is too easy to get the right answer to the wrong question. That's why InStat provides a unique analysis checklist. Double-check that your data have not violated any assumptions of the test, and that you have picked a test that matches your experimental design and really answers the question you had in mind.
