GraphPad Prism 5.0
Introduction
GraphPad Prism helps you organise, analyse and graph repeated experiments, pick appropriate statistical tests and interpret the results. This makes it ideally suited to data plotting and analysis applications in the life sciences.
What makes Prism truly unique, however, is not just what it does, but how it does it. Designed for laboratory and clinical researchers, Prism doesn't expect you to be a statistician. It guides you through the analysis process – giving you as much help as you need – and tracks and organises your work like no other program available. You can concentrate on your data, not on figuring out how to use the program.
Curve Fitting
Nonlinear regression fits a model to your data. You pick a model that corresponds to the experimental design from Prism's a menu of the 15 equations biologists use most, including those that describe dose-response curves, one- and two-site binding and competition, and one-and two-phase exponential association and decay. You can also enter your own equation.
Prism then automatically analyses an entire family of data sets at once. You don’t need to repeat any commands. Prism automatically creates the graph with curve, error bars and legend – ready to customise. The results are stores with your data and graphs, along with your analysis choices so you can inspect your choices and results at any time and add notes to explain what you did and what you concluded. When you repeat an experiment, simply replace the data, and Prism repeats all the analyses and redraws the graphs. You can instantly set up a template to analyse and graph your routine experiments, with no programming or macros.
Statistics
Prism makes it very easy to perform basic statistical tests commonly used by laboratory researchers and clinicians. It does not take the place of the big statistics programs, however it offers a complete set of statistical analyses up to two-way ANOVA, including analysis of contingency tables and survival curves. Prism does not perform ANOVA higher than two-way, or multiple, logistic or proportional hazards regression.
Experiment Organisation
With Prism you can store all parts of an experiment (several data tables linked to results, graphs, page layouts and notes) in one organised file. You can decide how much information to include in one project file. You can place all your data tables into one file, along with linked results and graphs. Or you can also separate your work into lots of files. Prism lets you choose how to organise your work.
