GraphPad Prism is a popular commercial statistics and graphing package, especially common in biology and biomedical labs. It combines guided statistical tests with publication-ready graphs in a point-and-click interface, so you can analyse and visualise data without scripting.

What Prism is good at
- Guided analysis — it helps you pick an appropriate test (t-tests, ANOVA, regression, survival, etc.).
- Curve fitting — nonlinear regression for dose-response, kinetics and binding, a standout feature.
- Publication graphs — clean, journal-ready figures linked to your data and analysis.
- Reproducible projects — data, analysis and graphs stay together in one file.
Is it free?
Prism is paid software (subscription), but GraphPad offers a free trial. If you need a free alternative, R (open-source, with ggplot2) covers the same analyses with more flexibility but a steeper learning curve.
Who it’s for
Bench scientists who want reliable, guided statistics and great graphs quickly. For large datasets, automation or custom methods, R is the more flexible choice; many labs use Prism for figures and R for heavier analysis.
Frequently asked questions
Is GraphPad Prism free?
No, it is paid (subscription), but a free trial is available from GraphPad.
What is Prism best at?
Guided statistical tests, nonlinear curve fitting, and publication-quality graphs tied to your data.
What’s a free alternative to Prism?
R with ggplot2 is the main free, open-source alternative; it is more flexible but requires coding.
