Stereology is the science of estimating geometrical quantities. The common geometrical quantities are numbers of things, length, area, and volume. Examples are number of cells in a brain, length of a seedling's roots, total area used for grazing in North America, fraction of a rock that is quartz. All of these quantities are too tedious to measure exactly so estimation is used. Stereology offers methods to determine: 1) an estimate of the quantity 2) an estimate of how good the estimate is believed to be. For example, this rock is 60% quartz give or take 5%. Stereology is used in fields such as biology, histology, pathology, metallurgy, geology, and forestry.
