Grow germination trial comparison calculator

Calculate observed germination fractions and Wilson95 intervals and difference from first treatment with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use observed germination fractions and Wilson95 intervals and difference from first treatment to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Observed germination fractions and Wilson95 intervals

Per treatment binomial intervals under independent seed assumption.

Difference from first treatment

Each observed proportion minus first-treatment observed proportion; no causal significance claim.

Assumptions & limits

Assumptions & limits

  • Seeds sown-germinated by treatment. Returns Observed rates and uncertainty. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification.
