Post-hoc Excel Analysis
Analyze any type of data with Sourcetable. Talk to Sourcetable's AI chatbot to tell it what analysis you want to run, and watch Sourcetable do the rest.
Introduction
Post-hoc analysis in Excel traditionally requires QI Macros add-ons to compare means using factors like LSD, HSD, and Scheffe's. These tests determine statistical significance by comparing p-values to significance levels, helping researchers identify which means differ significantly. While Excel's native data analysis tools cannot perform these tests, modern AI alternatives are revolutionizing how we conduct post-hoc analysis.
Sourcetable emerges as a powerful AI spreadsheet that eliminates the need for complex Excel functions and formulas. By conversing with an AI chatbot, users can analyze uploaded files or connected databases through natural language requests. The platform handles data analysis, visualization, and statistical testing without requiring technical expertise, making post-hoc analysis accessible to everyone.
In the following sections, we'll explore how Sourcetable streamlines post-hoc analysis with its AI-powered interface, which you can experience firsthand at https://app.sourcetable.com/signup.

Frequently Asked Questions
What is post-hoc analysis and when should I use it?
Post-hoc analysis is a statistical analysis performed after seeing the data to uncover differences between group means. It is commonly used when an ANOVA test is significant and the null hypothesis is rejected, particularly in studies investigating differences between groups or in clinical trials.
What post-hoc tests are available and how do I choose?
Common post-hoc tests include the Holm-Bonferroni Procedure, Newman-Keuls, Rodger's Method, and Scheffé's Method. These tests should be specified a priori (before analysis) to avoid HARKing (testing hypotheses suggested by the data).
How can I perform post-hoc analysis in Sourcetable?
You can perform post-hoc analysis in Sourcetable by simply uploading your data file or connecting your database, then asking the AI chatbot to conduct the analysis for you. Instead of manually running statistical functions, you can describe what analysis you want in natural language, and Sourcetable's AI will handle the technical details for you.
How can I visualize post-hoc analysis results in Sourcetable?
After performing your analysis in Sourcetable, you can ask its AI chatbot to create visualizations of your results. Simply describe the type of visualization you want (such as bar plots with p-values and error bars), and Sourcetable's AI will generate stunning charts that effectively communicate your findings.
Conclusion
Post-hoc analysis is essential for understanding which group means differ significantly after an ANOVA test.
