The Columbia sheep are dual-purpose animals.

Standard Deviation (SD) • This is a measurement of the variation of wool fiber diameter. • This is a quick and easy way to view the variability of fiber diameter within a sample. A ram must meet all of the following criteria while part of a CSBA approved ram test to achieve Certified Columbia Ram status. • For example – a sample with an AFD of 22.5 micron and a SD of 4.5 micron would have 2/3’s of the fibers measured between 18 and 27 micron.

Get Help. Uses. The higher the height of the “bar,” the more fibers have been measured in that group. They can be the construct of wood, wire, stone and other rustic materials. • The smaller the SD, the closer the fibers are to the Average Fiber Diameter, resulting in less variation among the individual fiber diameters for the entire sample. Histogram • This is a graph that shows the individual fiber diameter measurements of a sample. Aide.
