Need more than the free version?
Free is fine for quick fixes. We built Core and Premium to save you time and help avoid APA ambushes.
Free Tool
Work through the core assumptions of linear regression, record what you found, and generate a short summary you can use in your notes. This free version is built for checking and organising judgement, not for full tailored reporting.
Check each assumption
Move through the assumptions one by one, mark whether each one looks fine, unclear, or potentially problematic, then generate a brief summary at the end.

How to check it
Common warning signs
Regression Assumption Checker
Check the main assumptions of regression analysis with this free Regression Assumption Checker. Useful for psychology students working through linear regression, model validity, and the awkward question of whether the analysis is actually defensible.
