Which Leaves Stand for the Lot

A nested sampling design for the phenolic assay of dried guava leaf lots

A research poster from the School of Underlying Conditions partitions the variance in a smallholder drying shed's total-phenolic release assay across 24 guava trees, their branches, individual leaves and duplicate assays (432 assays), finding 65 per cent of it at the leaf. A ten-tree, thirty-leaf ground composite assayed twice more than halves the standard error of the lot mean that the shed's three-leaf, nine-assay plan achieves.
