| rank-difference correlation | The relationship between paired series of measurements, each ranked according to magnitude, which yields a coefficient known as rho; the value of rho varies from zero (no relationship) to +1.00 (perfect relationship). (05 Mar 2000) |

| correlation | <statistics> most generally, the degree to which one phenomenon or random variable is associated with or can be predicted from another. In statistics, correlation usually refers to the degree to which a linear predictive relationship exists between random variables, as measured by a correlation coefficient. Correlation may be positive, i.e., both variables increase or decrease together or negative or inverse, i.e., one variable increases when the other decreases. (18 Nov 1997) |
| correlation coefficient | A measure of association that indicates the degree to which two variables have a linear relationship; this coefficient, represented by the letter r, can vary between +1 and -1; when r = +1, there is a perfect positive linear relationship in which one variable relates directly with the other; when r = -1, there is a perfect negative linear relationship between the variables. (05 Mar 2000) |
| product-moment correlation | A statistical procedure which yields the correlation coefficient referred to as r (-1.00 to +1.00) and involves the actual values, rather than the ranks (rank order) of the measurements. (05 Mar 2000) |
| absolute zero | <chemistry, physics> This is the lowest possible temperature (0 Kelvin, -273.15 degrees Celsius, -459.67 degrees Fahrenheit). at this temperature, all molecular motion stops. (15 Jan 1998) |
| Patient Zero | The individual identified in 1982 by the Centres for Disease Control as responsible for introducing the HIV virus into the U.S. Population. A Canadian citisen, Patient Zero was a homosexual airline steward who claimed to have had as many as 2,500 sexual encounters. CDC epidemiologists located 19 men in Los Angeles, 22 in New York City, and 8 in other cities who had contracted AIDS from contact with Patient Zero, the earliest known cases of the disease in the U.S. Revealed to be Gaetan Dugas, Patient Zero died in 1984 due to AIDS-related illness. (05 Mar 2000) |
| protein Zero | <protein> The major glycoprotein of peripheral nerve myelin, an integral transmembrane protein, synthesised by Schwann cells (Mw = 28, 500). (18 Nov 1997) |
| zero | Origin: F. Zero, from Ar. Cafrun, cifrun, empty, a cipher. Cf. Cipher. 1. <mathematics> A cipher; nothing; naught. 2. The point from which the graduation of a scale, as of a thermometer, commences. Zero in the Centigrade, or Celsius thermometer, and in the Reaumur thermometer, is at the point at which water congeals. The zero of the Fahrenheit thermometer is fixed at the point at which the mercury stands when immersed in a mixture of snow and common salt. In Wedgwood's pyrometer, the zero corresponds with 1077 deg on the Fahrenheit scale. 3. The lowest point; the point of exhaustion; as, his patience had nearly reached zero. Absolute zero. See Absolute. <physics> Zero method, a method of comparing, or measuring, forces, electric currents, etc, by so opposing them that the pointer of an indicating apparatus, or the needle of a galvanometer, remains at, or is brought to, zero, as contrasted with methods in which the deflection is observed directly; called also null method. Zero point, the point indicating zero, or the commencement of a scale or reckoning. Source: Websters Dictionary (01 Mar 1998) |
| zero degree teeth | Prosthetic teeth having no cusp angles in relation to the horizontal. (05 Mar 2000) |
| zero end-expiratory pressure | Airway pressure which, at the end of expiration, equals atmospheric pressure. (05 Mar 2000) |
| zero energy thermonuclear assembly | <radiobiology> A British fusion device in which scientists observed fusion neutrons in 1958. They were erroneously considered to be thermonuclear (coming from particles with a Maxwellian velocity distribution) and were a cause for the initial optimism that fusion energy would be easy. They were actually due to electromagnetic acceleration during a plasma instability, an effect which cannot be scaled up to produce useful energy. (09 Oct 1997) |
| zero gravity | A physical state existing in space or at a time in flight when the centrifugal thrust of a parabolic glide or turn exactly counteracts the force of gravity. (05 Mar 2000) |
| zero-order reaction | A reaction that proceeds at a particular rate independently of the concentration of the reactant or reactants. (05 Mar 2000) |
| zero time-binding DNA | DNA that has become the duplex form at the start of a reassociation process. Acronym: DNA (05 Mar 2000) |
