Sure, a spreadsheet can surface bias if you set it up right. Create a clean contingency table of true positives, false positives, etc., broken down by demographic group. Then run a chi‑square test to see if the distributions differ significantly. Just remember that a small sample size or unmeasured confounders can still throw off the numbers. Also, as a footnote in Hume’s work reminds us, statistical inference is only as good as the assumptions you make.
