Popis:	The average staple length of merino fleece wool is 84 mm. Subjective classification of diameter–style groupings from one selling centre into ‘long’, ‘medium’, and ‘short’ produces differences of 7–8 mm between adjacent length categories. Sale lots within these length categories vary by ± 14 mm (95% confidence interval), so there is considerable overlap even between ‘long’ and ‘short’ wools. Individual staples within a sale lot vary by ± 25 mm about the mean (95% confidence interval). These estimates vary significantly with diameter and style category and among selling centres.
