Twelve bales of cotton having a wide range of lengths were selected for testing. Each bale was systematically sectioned so as to collect twenty-five individual fiber samples from each bale. HVI and AFIS measurements were carried out on each bale to determine the variability of the various measured properties with the bales. Variance components analysis was conducted to determine the relative impact of sample location, instrumental measurement, or the cotton itself.
