## parameter

[pah-ram´ĕ-ter]
1. in a mathematical expression, a constant that distinguishes specific cases, having a definite fixed value in one case but different values in other cases.
2. in statistics, a value that specifies one of the members of a family of probability distributions, such as the mean or the standard deviation.
3. a variable whose measure is indicative of a quantity or function that cannot itself be directly determined precisely.

## pa·ram·e·ter

(pă-ram'ĕ-tĕr), Avoid the jargonistic use of this word to mean simply 'something measured or measurable'. One of many dimensions or ways of measuring or describing an object or evaluating a subject:
1. In a mathematic expression, an arbitrary constant that can possess different values (with each value defining other expressions), and can thereby determine the specific form but not the general nature of the expression; for example, in the equation y = a + bx, a and b are parameters.
2. In statistics, a term used to define a characteristic of a population, in contrast to a sample from that population, for example, the mean and standard deviation of a total population.
3. In psychoanalysis, any tactic, other than interpretation, used by the analyst to further the patient's progress.
[para- + G. metron, measure]

## parameter

[pəram′ətər]
Etymology: Gk, para + metron, measure
1 a value or constant used to describe or measure a set of data representing a physiological function or system, as in the use of acid-base relationships of the blood as parameters for evaluating the function of a patient's respiratory system.
2 a statistical value of a population group.

Usage notes: (informal)
limit or boundary.

## parameter

A mathematical and statistical variable in a model system that partially or completely characterises a probability distribution. Parameters are rarely known and are usually estimated by statistical computation from samples. In clinical trials, parameter may be used synonymously with variable for factual data—e.g., age, date of recovery, measurements and clinical assessments; however, it is most often linked to statistical conventions as a numeric characteristic of a population and thus has a narrower definition than variable.

## parameter (pəram´ətur),

n the values that refer to a population; characteristics of a population. Because a parameter is a value of a hypothetical, infinite, unknown population, it is always an estimate.
Paramyxoviridae
n one of the major ribonucleic acid virus families, to which the measles, mumps, parainfluenza, and respiratory syncytial viruses belong. Viruses in this family have a single-stranded, nonsegmented, linear molecular structure with helical symmetry.

## parameter

1. in mathematics and statistics, an arbitrary constant, such as a population mean or standard deviation. It wholly or partly determines a probability distribution.
2. a property of a system that can be measured numerically.

Two additional bits of evidence from the PARM study support and extend this interpretation.
An ad-by-ad comparison of recognition and recall scores in the PARM data sheds some light on this question.
This interpretation is supported by the relation in the PARM data between two kinds of recognition scores: Noted scores and Seen-Associated scores.
One further bit of evidence from the PARM study also supports this idea.
In an effort to replicate this finding and to further clarify the relationship between recognition and recall, the scales measuring meaningfulness and attractiveness were used to rate ten specially selected pairs of PARM ads.
The correlations between the rating scale scores and the PARM recognition and recall scores are shown in Table 5.
