GraphPad Prism - analyze, graph and organize your data

Prism is a powerful combination of basic biostatistics, curve fitting (nonlinear regression) and scientific graphing in one comprehensive program.
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.

Curve fitting
Prism fits the curve, displays the results as a table, and draws the curve on the graph.
It also gives you many advanced fitting options - automatically interpolate unknown values from a standard curve (i.e., to analyze RIA data), compare two equations with an F test or Akaike's Information Criterion (AIC), and plot residuals.

Statistics
Prism lets you easily perform basic statistical tests commonly used by laboratory and clinical researchers.
It offers tests, nonparametric comparisons, one- and two-way ANOVA, linear and nonlinear regression, analysis of contingency tables, and survival analysis.

Scientific graphing
Prism makes a wide variety of 2D scientific graphs, giving you all the features you need - including automatic error bars, log axes, discontinuous axes, Greek letters and much more.

Organizing experiments
Prism understands the links between data and analyses, and stores your related data, analysis results, graphs, layouts and notes in one efficient project file.
