The state or characteristic of being variable.

definition

The degree to which a thing is variable. In data or statistics this is often a measurement of distance from the mean or a description of data range.

Note the very large standard deviations in Table 1, showing great variability.

However, the range of variability in fractured vertebrae would pose a problem for a global model.

The variability of an array of such a table-that is, of any line or column of it-is the mean variability of pairs of leaves, each pair chosen from one tree, and having one leaf of a particular character; it may therefore be taken as a fair measure of the variability of such a tree.

There is therefore in a large class, of cases an indication that the variability of an array of brethren, produced either sexually or asexually, is a constant fraction of the variability of the race to which the brethren belong.

Temporal and spatial variability was less evident for algae attached to rocks.

Also, the net is very tolerant of temporal variability in the signal.

Families of triploid salmon were found to have much greater variability in growth than fertile diploids [7 ].

A common disadvantage of wind power has been wind variability.

The newer version, which is available for both Linux and Mac, overcomes some of the hardware limitations that gamers faced in the mid-90s, expanding the game to allow for more vehicles, more variability, and more options.

In addition, this variability also hinders clinical research.

Renal vein thrombosis is more common in patients with nephrotic syndrome, although studies have shown high variability among these patients, with rates of 5 to 62 percent reported.

However, the RDA values are actually greater than the minimal requirement, as determined by studies on small groups of healthy human subjects, in order to accommodate the variability expected among the general population.

Other indicators of fetal well-being include short term variability (STV), which constitutes changes in the FHR from one beat to another, and long term variability (LTV), which is changes in the FHR over a long period of time.

There is a great deal of variability in the severity of symptoms, which can range from clinically insignificant to life threatening.

There is a great deal of variability in the timing of engagement parties.

There is a lot of variability in the size of these flaws and their location within a stone.

But the causes and conditions of variation have yet to be thoroughly explored; and the importance of natural selection will not be impaired, even if further inquiries should prove that variability is definite, and is determined in certain directions rather than in others, by conditions inherent in that which varies.

In the latter case the organization seems to become plastic, and we have much fluctuating variability.

A transformation which is sometimes rapid, sometimes slow, but always continuous, is wrought by the reciprocal action of the innate variability of plants and of the variability of the external factors.

He proclaimed the variability of species in opposition to the views of Linnaeus as to their fixity, and moreover supposed that this variability arose in part by degradation.

The conclusions deducible from their anthropological features - apart from the general difficulty of arriving at safe conclusions on this ground alone, on account of the variability of the ethnological type under various conditions of life - are also rather indefinite.

It was difficult to be sure as to the variations in the actual number of fish caught, but it was easy to show that there was a real variability in the yield of cod-liver oil (an important product of the fishery).

Later still Hjort showed that the study of the variability in the productivity of a fishery is always a complex matter - far more so than was formerly supposed.

Thus the field of disease arising not from essential defect in the body, but from external contingencies, is vastly enlarging; while on the other hand the great variability of individuals in susceptibility explains the very variable results of such extrinsic causes.

In modern thermometry instruments of extreme accuracy are required, and researches have been made, especially in Germany and France, to ascertain the causes of variability in mercurial thermometers, and how such variability is to be removed or reduced.

Both in size and form considerable variability is displayed, the species of Holochilus being some of the largest, while the common white-footed mouse (Eligmodon leucopus) of North America is one of the smaller forms. Some kinds, such as Oryzomys and Peromyscus have long, rat-like tails, while others, like Acodon, are short-tailed and more volelike in appearance.

Deperet notes that the genus Neumayria, an ammonite of the Kimmeridgian, suddenly branches out into an explosion" of forms. Deperet also observes the contrast between periods of quiescence and limited variability and periods of sudden efflorescence.

Among the ammonites the loss of power to coil the shell is one feature of racial old age, and in others old age is accompanied by closer coiling and loss of surface ornamentation, such as spines, ribs, spirals; while in other forms an arresting of variability precedes extinction.

Brocchi and Daniel Rosa (1899) have developed the hypothesis of the progressive reduction of variability.

Such decline is by no means a universal law of life, however, because among many of the continental vertebrates at least we observe extinctions repeatedly occurring during the expression of maximum variability.

Internal causes of extinction are to be found in exaggeration of body size, in the hypertrophy or over-specialization of certain organs, in the irreversibility of evolution, and possibly, although this has not been demonstrated, in a progressive reduction of variability.

The tongue presents little variability in length, being short and compressed, with a blunt tip, which is never protruded beyond the incisors.

This curious variability, deserving more attention than it has yet received, only occurs in the outer feathers of the series, which are narrow in form and extremely stiff, there being always 10 in the middle of ordinary breadth.

It is to the different characters of the stations they occupy with respect to exposure, moisture, &c., that the variability observed in many types of lichens is to be attributed.

This has been more especially the case when the auroral light has been of a diffused character, showing only minor variability.

He insisted that the great powers of increase of all organisms led to a tremendous struggle for existence, and that variability extended to every part and organ of every organism; that the variability was large in amount in proportion to the size of the part affected, and occurred in a considerable proportion of the individuals of those large and dominant species which might be supposed to be breaking up into new species.

The variability of structures which are repeated in the body of the same individual (serial homologues) has been studied by Pearson and his pupils with important results.

We see therefore that while leaves, gathered in equal numbers from each of loo trees, are distributed about their mean with a standard deviation of 1.735 veins, the leaves gathered from a single tree are distributed about their mean with a standard deviation of 1.426 veins, the ratio between variability of the race and variability of the individual tree being 1 - (0-5699)1=0.822.

We may therefore conclude that for large classes of characters, both animal and vegetable, the variability of an individual, as measured by the standard deviation of its undifferentiated but repeated organs, is a constant fraction of the variability of its race, as measured by the standard deviation of the corresponding series of organs produced by all the individuals of its race.

The evidence that the correlation between sexually produced brethren is the same as that existing between the asexually repeated organs on an individual body renders it impossible to accept Weismann's view that one of the results produced by the differentiation of animals and plants into two sexes is an increase in the variability of their offspring.

The question of a possible variability in the length of the day is one of fundamental importance.

There is some over-lapping of these two classes as regards length of period, and it is doubtful in which class some stars, whose periods are between io days and 150 days, should be placed; but the two classes are quite distinct physically, and the variability depends on entirely different causes.

In both cases no extraneous cause can be assigned; the period seems to be inherent in the star itself and not to be determined by the revolution of a satellite (no variability of the line-of-sight motion of Mira has been found, so that it is probably not accompanied by any large companion).

The extreme variability in the amount of rainfall is remarkable.'

The greatest variability in temperature conditions in the state occurs in the Blue Ridge, Newer Appalachian Provinces, where the most rugged and variable topography is likewise found.

Owing to its variability in this respect, and to its insolubility, certain other salts have largely replaced the sulphate in modern medicine.
