This simple stereological procedure does not provide the mean diameter of the tree trunk.
At pi centimeters write 1, at 2pi centimeters write 2, and so forth to make a tape where the measurements taken do not require the additional step of dividing by pi. Another way to do this is to make a tape measure that is in units of pi. Divide that by pi to obtain the mean diameter of the tree trunk. The method selected to determine mean diameter is to wrap a tape around the tree and to read off the length. A question that can be asked of the trees is the mean diameter of the trees. There is a tract of land with trees on it. Most people do not understand what is required but are able to enter some numbers and then see one or more numbers spit out by the black box.Ĭonsider the follow simple problem. For many people stereology is a black box.
