Overview
GraphPad Prism
GraphPad Prism combines scientific graphing, comprehensive curve fitting, and understandable statistics into one organized program. You can move from raw data to finished analysis and professional graphs in minutes. Unlike complex statistical packages, it guides you through the process by asking what kind of data you have and suggesting appropriate tests. You can perform everything from basic t-tests and one-way ANOVA to advanced nonlinear regression and survival analysis.
The software is built for scientists, not statisticians, making it ideal for laboratory researchers, clinicians, and students across life sciences and social sciences. You can automate your workflow by creating templates that update your graphs and results automatically when you add new data. It ensures your work is reproducible and ready for high-impact journals with flexible export options and rigorous statistical validation.
SPC for Excel
SPC for Excel transforms your familiar spreadsheet environment into a powerful statistical analysis tool. You can stop toggling between different applications and perform all your Six Sigma, Lean, and quality control calculations directly within Excel. It simplifies the process of creating professional control charts, performing Pareto analysis, and conducting Gage R&R studies with just a few clicks.
You can easily identify process trends, monitor stability, and determine capability using automated tools that handle the underlying mathematics for you. Whether you are a quality engineer, a green belt, or a researcher, this software provides the statistical depth you need without the steep learning curve of standalone statistical packages. It is designed to help you make data-driven decisions quickly while keeping your data in its original Excel format.
