GraphPad InStat is a commercial scientific statistics software available for both Windows and Macintosh computers.

Features[edit]

InStat is designed for statistical novices. It helps you pick an appropriate test by asking questions about the data. 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, and provide unique analysis checklists to confirm that the data have not violated any assumptions of the test, and that the test answers the right question.
