| frequency | 1. <physics> The number of occurrences of a periodic or recurrent process per unit time, for example the number of vibrations of a particle per second or the number of repetitions of a complete wave form (cycles) per second. 2. <statistics> The number of members of a population or statistical sample falling in a particular class. 3. Relative frequency, the average number of occurrences of a particular event in a large number of repeated trials. (07 Apr 1998) |
|---|---|
| frequency analysis | <ecology, statistics> A method of evaluating vegetation in an area by establishing a transect and counting the occurrences of plant species at various sampling points along the transect. (07 Apr 1998) |
| frequency curve | A systematic grouping of data into classes or categories according to the frequency of occurrence of each successive value or ranges of such values, resulting in a graph of a frequency distribution. Synonym: frequency curve. (05 Mar 2000) |
| frequency distribution | A statistical description of raw data in terms of the number or frequency of items characterised by each of a series or range of values of a continuous variable. (05 Mar 2000) |
| frequency domain | The expression of a function by its amplitude and phase at each component frequency, usually as determined by Fourier analysis. (05 Mar 2000) |
| frequency encoding | In magnetic resonance imaging, a method of varying the magnetic field strength with location to encode the location of each voxel uniquely in one direction. (05 Mar 2000) |
| frequency of micturition | Micturition at short intervals; it may result from increased urine formation, decreased bladder capacity, or lower urinary tract irritation. (05 Mar 2000) |
| frequency of occurrence | The number of times a given event occurs at specified sample points during a defined period. (07 Apr 1998) |
| frequency spectrum | The range of frequencies in a signal, used to describe the resolving power of an imaging system in radiology. (05 Mar 2000) |
| frequency, urinary | Urinating too often, at too frequent intervals, not due to an unusually large volume of urine, but rather to a decrease in the capacity of the bladder to hold urine. (12 Dec 1998) |
| frequenin | <immunology> A water in oil emulsion used experimentally for stimulating a vigorous immune response to an antigen (that is in the aqueous phase). Complete Freund's adjuvant contains heat killed tubercle bacilli, these are omitted from Freund's incomplete adjuvant. Unsuitable for use in humans because it elicits a severe granulomatous reaction. (18 Nov 1997) |
| frequent | 1. Often to be met with; happening at short intervals; often repeated or occurring; as, frequent visits. "Frequent feudal towers." 2. Addicted to any course of conduct; inclined to indulge in any practice; habitual; persistent. "He has been loud and frequent in declaring himself hearty for the government." (Swift) 3. Full; crowded; thronged. "'T is Caesar's will to have a frequent senate." (B. Jonson) 4. Often or commonly reported. "'T is frequent in the city he hath subdued The Catti and the Daci." (Massinger) Origin: L. Frequens, -entis, crowded, frequent, akin to farcire to stuff: cf. F. Frequent. Cf. Farce. 1. To visit often; to resort to often or habitually. "He frequented the court of Augustus." (Dryden) 2. To make full; to fill. "With their sighs the air Frequenting, sent from hearts contrite." (Milton) Origin: L. Frequentare: cf. F. Frequenter. See Frequent. Source: Websters Dictionary (01 Mar 1998) |
| frequent flooding | <ecology> Flooding which is likely to occur often during usual weather conditions (i.e., more than a 50 percent chance of flooding in any year, or more than 50 times in 100 years). (09 Oct 1997) |
| frequenter | One who frequents; one who often visits, or resorts to customarily. Source: Websters Dictionary (01 Mar 1998) |

| frequency distribution |
In statistics, a frequency distribution is a list of the values that a variable takes in a sample. It is usually a list, ordered by quantity, showing the number of times each value appears. ...

| frequency distribution |
1. A curve the coordinates of which are the values of the variable and the frequency of occurrence. It is often presented as a histogram. Compare probability distribution. 2. (Also called frequency curve.) The relationship between the probability that a threshold is exceeded and the threshold. In a graphical representation, the curve is often plotted with frequency or probability on the vertical y axis and the corresponding rainfall or flood flow values on the horizontal x axis.
