Decile
One of ten equal-sized groups a sorted data set is divided into -- the 10th, 20th, 30th... percentile cut points. Compound pages chart dose deciles to show the full shape of the market's dose distribution, not just a single median number.
Example
Magnesium's dose deciles run from a 10th-percentile dose well below the RDA up to a 90th-percentile dose that starts to approach it.
