A sample of scores has a mean equal to M and a standard deviation equal to S. From each score in the sample one standard deviation (S) is subtracted. After this transformation, the standard deviation of the sample of scores is equal to:

Radii ok and nl are perpendicular to om because of the radius-tangent theorem. by definition of perpendicular, angles kom and lnm are right angles. this means that triangles kom and lnm are right triangles. angle lmn is common to both right triangles, so by the triangles kom and lnm are similar.
