Learn the skill

Count sprouted seeds over all seeds in the stated trial, including those that did not sprout. Multiply that fraction by 100 for a percentage. A trial percentage does not guarantee a future batch will match. All counts are invented.

Worked example

If 15 of 20 seeds sprout, the trial percentage is 15/20 x 100 = 75%. The denominator is not just successful seeds.

A four-row, five-column seed record shows 20 positions. Fifteen are marked S for sprouted and five with a dash for not yet sprouted. The trial proportion is 15/20, or 75%.
