Summary

A comparison of objective and subjective appraisals of the yield of Australian greasy wool sale lots is reported.

Results suggest that although the overall agreement between the two systems of appraisal is good, the subjective estimate of an individual sale lot will only lie within ± 6% of the objective estimate in 95% of cases.
