GraphPad Prism vs Excel: Which is Better for Science?
Every scientist starts with Excel. It's ubiquitous, flexible, and easy to use. But as your research advances, you'll likely hear about GraphPad Prism. Is it worth the switch? And is there a modern alternative that combines the best of both?
Microsoft Excel: The Jack of All Trades
Excel is a spreadsheet program, not a scientific plotting tool.
Pros
- Installed on almost every computer.
- Great for data entry and basic manipulation.
- Flexible cell-based calculations.
Cons
- Terrible Plots: Default charts look "corporate," not scientific.
- No Statistics: Performing t-tests or ANOVA requires complex add-ins or formulas.
- Hard to Reproduce: Click-and-drag formatting is lost if you change data.
GraphPad Prism: The Specialist
Prism is designed specifically for experimental biologists. It combines statistics, curve fitting, and graphing.
Pros
- Integrated Stats: Automatically runs t-tests/ANOVA when you plot.
- Scientific Defaults: Plots look good out of the box.
- Guidance: Helps you choose the right statistical test.
Cons
- Expensive: Subscription-based (~$200/year for academics).
- Rigid: Hard to customize beyond standard templates.
- Proprietary: Files can only be opened with Prism.
The Verdict
Use Excel for data entry. Use Prism (or an alternative) for plotting and stats.
Trying to force Excel to make publication-quality violin plots or survival curves is a recipe for frustration. It simply isn't built for it.
Is There a Better Way?
What if you could have the ubiquity of a web app (like Excel Online) with the scientific power of Prism?
