- The result of mathematical division. The I.Q. (Intelligence Quotient) is arrived at by dividing the person's mental age (as determined on the Binet test) by the person's chronologic age and multiplying by 100. So if a child scores at the 8-year old level but is only 6, the I.Q. is 8/6 X 100=125.
* * *The number of times one amount is contained in another; the ratio of two numbers. SEE ALSO: index (2), ratio. [L. quoties, how often]- achievement q. a ratio, percentile rating, or related q. denoting the amount a child has learned in relation to peers of his or her age or level of education.- cognitive laterality q. (CLQ) test for difference in cognitive performance of left and right sides of the brain.- extremal q. the ratio of the rate in the jurisdiction with the highest rate of interventions such as surgical procedures to the rate in the jurisdiction with the lowest rate.- intelligence q. (IQ) the psychologist's index of measured intelligence as one part of a two-part determination of intelligence, the other part being an index of adaptive behavior and including such criteria as school grades or work performance. IQ is a score, or similar quantitative index, used to denote a person's standing relative to age peers on a test of general ability, ordinarily expressed as a ratio between the person's score on a given test and the score that the average individual of comparable age attained on the same test, the ratio being computed by the psychologist or determined from a table of age norms, such as the various Wechsler intelligence scales.- Meyerhof oxidation q. an index for the effect of oxygen on glycolysis and on fermentation ( I.E., on the Pasteur effect); equal to the rate of anaerobic fermentation minus the rate of aerobic respiration divided by the rate of oxygen uptake.- P/O q. SYN: P/O ratio.- protein q. the number obtained by dividing the quantity of globulin of the blood plasma by the quantity of albumin.- respiratory q. (R.Q.) the steady-state ratio of carbon dioxide produced by tissue metabolism to oxygen consumed in the same metabolism; for the whole body, normally about 0.82 under basal conditions; in the steady state, the respiratory q. is equal to the respiratory exchange ratio. SYN: respiratory coefficient.
* * *quo·tient 'kwō-shənt n the numerical ratio usu. multiplied by 100 between a test score and a measurement on which that score might be expected largely to depend
* * *quo·tient (kwoґshənt) a number obtained as the result of division; a number indicating how many times one number is contained in another.
