Verdict
The clearest difference is rating: Probability Distribution at 4.5 against Statistics Calculator Lite's 2.4. Probability Distribution also leads on update cadence (every 2 weeks vs every 12 months). Statistics Calculator Lite's advantage is in-app purchases (none vs 1) and iOS requirement (10.0 vs 16.0). On price, review sentiment, ratings volume and ads there is nothing between them.
