| antigenic variation | The phenomenon of changes in surface antigens in parasitic populations of Trypanosoma and Plasmodium (and some other parasitic protozoa) in order to escape immunological defense mechanisms. at least 100 different surface proteins have been found to appear and disappear during antigenic variation in a clone of trypanosomes. Each antigen is encoded in a separate gene. Antigenic variation is also known to occur in free living Protozoa and certain bacteria. (18 Nov 1997) |

| variation | In genetics, deviation in characters in an individual from those typical of the group to which it belongs, also, deviation in characters of the offspring from those of its parents. (18 Nov 1997) |
| variation (genetics) | The phenotypic differences among individuals in a population. (12 Dec 1998) |
| phase variation | <microbiology> Alteration in the expression of surface antigens by bacteria. For example: Salmonella can express either of two forms of flagellin, H1 and H2, that are coded by different genes. Control of which form is expressed is brought about by inversion of the promoter for the H2 gene, which if functional (noninverted) is associated with the expression of H2 and the production of a repressor of the H1 gene. Inversion occurs about every 1000 bacterial divisions and is under the control of another gene, hin, that is within the invertable sequence. (31 Dec 1997) |
| contingent negative variation | An increasing negative shift of the cortical electrical potentials associated with an anticipated response to an expected stimulus. It is an electrical event indicative of a state of readiness or expectancy. (12 Dec 1998) |
| somaclonal variation | The variation between individuals in a clone, particularly in plant clones. While the objective is usually to grow clones without variation, somaclonal variation does provide the opportunity to generate new plant types that would be harder or impossible to generate by conventional plant breeding. (14 Nov 1997) |
| isotypic variation | <immunology> Variability of antigens common to all members of a species, for example the five classes of immunoglobulins found in humans. See: idiotype and allotype. (18 Nov 1997) |
| observer variation | The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material). (12 Dec 1998) |
| absorption coefficient | <physics> Measures the degree of wave absorption defined as the fraction of wave energy lost as the wave travels a unit distance. See: absorption. (15 Jan 1998) |
| activity coefficient | <chemistry> The factor by which the value of a concentration of a solute must be multiplied to determine its true thermodynamic activity. (06 May 1997) |
| attenuation coefficient | 1. <radiobiology> Compton: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing as a result of Compton effect interactions. 2. Linear: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing due to all absorption and scattering processes. 3. Pair Production: That fractional decrease in the intensity of a beam of ionising radiation due to pair production in a medium through which it passes. 4. Photoelectric Effect: That fractional decrease in the intensity of a beam of ionising radiation due to photoelectric effect in a medium through which it passes. (16 Dec 1997) |

| velocity coefficient | The rate of transformation of a unit mass of substance in a chemical reaction. (05 Mar 2000) |
| recombination coefficient | <radiobiology> The rate of recombination of positive ions with electrons (or negative ions) in a gas, per unit volume, divided by the product of the particle densities of the two species (positive ions and electrons/negative ions) involved. (09 Oct 1997) |
| coefficient of variation |
(CV) the standard deviation divided by the mean, sometimes multiplied by 100; a unitless quantity indicating the variability around the mean in relation to the size of the mean.

| coefficient of variation |
The coefficient of variation (CV) indicates the quality of a population estimate. A CV of 16.7-25.5 indicates moderate sampling variability. A CV of 25.6-33.3 indicates high sampling variability. Estimates with either a moderate or high CV should be interpreted with caution. In some situations, the sample in the survey was too small to produce a reliable estimate. These numbers are not included in the report.

| coefficient of variation |
The measure of the ability to repeatedly obtain the same value for a single sample or method (ie; duplicate or replicate analyses). This may also be called the precision. [Note: Accuracy is not the point here, but rather how many times the same answer is obtained when all factors of the analysis remain constant ?same sample, same volume, same method, etc.] This value is calculated the same as a Relative Standard Deviation.

| coefficient of variation |
The ratio of the standard error for a variable to the mean value of the variable. This is used to measure the imprecision in survey estimates introduced by sampling. A coefficient of variation of 1 percent would indicate that an estimate could vary slightly due to sampling error, while a coefficient of variation of 50 percent means that the estimate is very imprecise. ...
