Prism combines powerful biostatistics, curve-fitting, and scientific-graphing tools in a comprehensive program. Prism meets virtually all of the data-handling needs of laboratory researchers, especially biologists. Prism makes it easy to create highly-customizable graphs that can be exported as high-resolution image files for publications, PowerPoint presentations, Web sites, Word documents, and more.
While the statistical features of Prism and InStat overlap, Prism has much more statistical depth. Prism, but not InStat, can fit curves with nonlinear regression, can create and compare survival curves, can calculate two-way ANOVA, can compare linear regression lines, and more.
Version 7 of GraphPad Prism introduces many improvements in graphs, nonlinear regression, statistical analyses and much more.
GraphPad Prism是一套結合圖的科學軟體可以用來產生高品質的科學圖表，在科學圖表的繪製方面可以視為Sigmaplot的替代軟體，但是卻又包含了簡單的試算表，可以直接輸入原始資料，軟體自動計算標準差和p value，此外，也包含了生物數理統計，曲線擬合，及圖表顯示功能，適用於生物數理統計實驗的資料處理。
GraphPad Prism is a powerful combination of basic biostatistics, curve fitting and scientific graphing in one comprehensive program. More than 100,000 scientists in over 100 countries rely on Prism to analyze, graph and present their scientific data.
What makes Prism the program of choice for many of the world's leading universities, medical centers, research institutes and pharmaceutical companies? Prism certainly has all the capabilities you would expect from a top notch scientific graphics program, but what makes Prism truly unique is not what it does, but how it does it. Designed for the practical scientist, Prism does not expect you to be a statistician. It guides you through each analysis - giving you as much help as you need - and tracks and organizes your work like no other program available. You can concentrate on your data, not fight with your software.
