Comparing Prism, InStat and StatMate


Prism GraphPad Prism combines powerful biostatistics, curve-fitting, and scientific-graphing tools in a single comprehensive program. Prism was created to meet virtually all of the data-handling needs of laboratory researchers, especially biologists. While the statistical features of Prism and InStat overlap, Prism does much more, including nonlinear regression, survival curves, two-way ANOVA, comparison of linear regression lines and more. (Prism, however, does not perform multiple regression while InStat does.)

Prism makes it easy to create highly-customizable graphs that can be exported as high-resolution image files for publication in PowerPoint presentations, Web sites, Word documents, and more. InStat provides only limited graphing capabilities.


InStat GraphPad InStat is a less cumbersome alternative to heavy-duty statistics programs. With InStat, even a statistical novice can analyze data in just a few minutes.

-- Enter your data, pick a statistical test, and get the result!

Even if you have a more powerful statistics program, you may still welcome InStat's simple step-by-step approach. Keep the big programs for complex problems, and zip through routine analyses with InStat.

InStat has only limited graphing capabilities compared to Prism. Some Prism users, however, prefer InStat's step-by-step approach to basic statistics when graphing isn't a priority.


StatMate GraphPad StatMate takes the guesswork out of evaluating how many data points you'll need for an experiment, and makes it easy for you to quickly calculate the power of an experiment to detect various hypothetical differences. It is an ideal companion to Prism and InStat.

StatMate's wizard-based format leads you through the necessary steps to determine the tradeoffs in terms of risks and costs. There is no learning curve with StatMate because it is self-explanatory. All the documentation you need is built right into the program.
