Why Researchers Choose GraphPad Prism
GraphPad Prism is the preferred statistical and graphing software among biomedical, clinical, and life science researchers. It combines powerful statistical analyses with publication-quality graphics β producing figures accepted by Nature, Science, Cell, and all major biomedical journals. Its guided interface makes it accessible even without a deep statistics background.
Understanding Prism's Data Table Structure
Unlike SPSS, Prism organizes data into pre-structured table types:
- XY: Scatter plots, time-course data, dose-response curves
- Column: Group comparisons (t-tests, ANOVA)
- Grouped: Two-way or factorial designs
- Contingency: Chi-square analysis
- Survival: Kaplan-Meier curves
Selecting the correct table type is the first and most critical step.
Running a T-Test and Creating a Figure
- Create a Column data table and enter each group's data in a separate column.
- Analyze β Column Analyses β t-test (unpaired or paired as appropriate).
- Prism automatically generates a figure linked to the data table.
- Double-click the graph to customize colors, symbols, axis formatting, and error bars.
- Add significance brackets: Analyze β Multiple Comparisons β Significance brackets.
Publication-Quality Figure Tips
- Font: Arial or Helvetica, 8β10pt (check target journal guidelines).
- Color: Use CMYK mode for print; confirm whether color figures are accepted.
- Export: TIFF format at 300+ DPI. File β Export β TIFF.
- Error bars: Always specify whether you're showing SD or SEM in the figure legend.
Kaplan-Meier Survival Analysis
Create a Survival data table. Each row contains: X (time), Group column, and Censored (0=event occurred, 1=censored). Analyze β Survival Curve automatically performs the Log-Rank test and provides Hazard Ratio with 95% CI.
