Browse the Statistics and Regression guides
This Prism Guide is only one of three guides. Check out the other two. Both do more than explain how to use Prism. They also explain the concepts of data analysis.

Step by step tours
Read this one page tour, which will take about five minutes to follow.
Then follow longer detailed tours that walk you step by step through data analyses and graphing.
Work with tutorial data sets
Choose these from the Welcome dialog. Each sample data set comes with brief instructions, and links to longer explanations.
The data table with sample data, also contains a floating note that explains how the data are arranged and gives suggestions for graphing and analyzing.
Follow stepbystep examples, using sample data, for analyzing data with Prism:
Descriptive statistics
Compare two groups
Categorical outcomes
Diagnostic lab tests
Nonlinear regression
Fitting an enzyme kinetics curve
Comparing two enzyme kinetics models
Automatic outlier elimination (exponential decay)
Global nonlinear regression (doseresponse curves)
Explore the graph portfolio
Choose the Portfolio tab at the bottom of the Welcome dialog to browse dozens of polished graphs, each of which demonstrates several Prism features. When you open a portfolio graph, you'll see a brief explanation of how that graph was made, and can explore the details. Many of these portfolio graphs are linked to stepbystep instructions. Others give brief explanations. Exploring these files will help you master graphing with Prism.
