Glossary Term
The ratio of standard deviation to mean, expressed as a percentage or fraction.
Technology
A type of spectroscopy that utilizes a laser beam to irradiate a sample containing particles in suspension, resulting in light scattering. Rapid fluctuations in scattering intensity, around a mean value at a certain angle, occur because of particle diffusion and are dependent upon on particle size. The calculated correlation function yields a diffusion coefficient, for a given temperature and viscosity, which can be used to calculate particle size.
Pruebas
An index of the variation in the size of the red cells and can be used to detect subtle degress of anisocytosis. It is computed directly from the RBC histogram and is calculated as a standard statictical value, the coefficient of variation of the red cell volume ditribution (ratio of standard deviation and mean copuscular volume).
Glossary Term
A measure of the correlation of two variables X and Y measured on the same object or organism, that is, a measure of the tendency of the variables to increase or decrease together. It is defined as the sum of the products of the standard scores of the two measures divided by the degrees of freedom.
