Elements and Performance Criteria
- Prepare a working sample
- Count and weigh seed by machine
- Count and weigh replicates by hand
- Count out eight replicates of 100 seeds randomly from the working sample
- Weigh each replicate to the required number of decimal places
- Record weights of each replicate
- Calculate variance, standard deviation and coefficient of variance
- Test a new set of replicates where the coefficient of variance exceeds the prescribed value
- Determine the average weight of 1000 seeds where the coefficient of variance does not exceed the prescribed value
- Report results
