unevenness: the quality of being uneven and lacking uniformity
the state or characteristic of being variable; the degree to which a thing is variable
The degree to which differences exist among a set of scores. The standard deviation is usually used to describe the variability of scores in a sample.
A spread of possible outcomes around an expected outcome.
The possible different outcomes of an event. As an example, an investment with many different levels of return would have great variability.
the use of the substance. Everything in the universe is continually changing. By comprehending this one may realize the importance of flexibility in life and may thus cultivate the proper attitude for dealing with a multiplicity of diverse situations.
In normal healthy volunteers, the intra-individual variabilities of C max , AUC, and CL/f for glimepiride were 23%, 17%, and 15%, respectively, and the inter-individual variabilities were 25%, 29%, and 24%, respectively.
When used in reference to climate, variability refers to the tendency of conditions to vary around some reference point (such as the tendency of the temperature to deviate from some average).
"Noise" due to random (chance) and non-random (systematic) factors that obscure the actual factor of interest.
A program part which is expected to change, due to hardware/software reconfiguration, changing user requirements, new languages, marketing demands, etc. A function argument or global constant is a variability, as is, to some degree, a well-structured loop which allows editing its endpoints. ...
The characteristic of a product or process in which parameters fluctuate to a significant degree but do not typically trend in a specific direction. Reduction of variability is a priority in systems that attempt to ensure consistent quality and reduce lead times.
Differing from the average value. Absence of uniformity, usually referring to lack of genetic uniformity in a population. (See heterozygosity and resilience.)
in statistics, the dispersion of scores within a set of data.
The quality of being likely to change or vary over time; lack of uniformity. There are two types of variability: temporal and spatial. ...
Language learners vary in the use they make of their linguistic knowledge. This can be systematic or unsystematic.
The extent to which scores differ from one another.
Most measured variables show some variation, i.e. their values are not constant
The range of abiotic conditions in an environment. 
A characteristic of a domain that corresponds to features that distinguish among members of the associated family of systems. See Commonality.
The Load Variation of a Variable Spring Hanger divided by the Hot Load expressed as a percentage.
Differing rhythmicity or changes in condition; often used to describe fetal heart rate reflected on the fetal heart rate tracing as a slight irregularity or jitteriness.
Students cannot understand the purpose of statistics unless they get the concept of variability. Within this, we can further talk about variability due to chance and variability due to effect. ...
The differences in the measurement of variables, thus the differences between sample and population values or among samples drawn from the same population.
The property or ability of an organism to change its characteristics from one generation to the other.
