degree to which something changes
How much something changes instead of staying the same.
用法パターン：
variability in [something]
よくある間違い：
Learners often confuse "variability" with "variety". "Variability" is usually uncountable and describes how much something changes (e.g., "high variability in temperature"). "Variety" refers to different kinds or types of something (e.g., "a wide variety of foods"). Learners also sometimes say *"a variability"* in general statements, where natural English uses uncountable "variability" without an article.
類義語
changeability (Very close in meaning, but slightly more informal and less often used in technical writing.)

inconsistency (Often suggests an undesirable or problematic kind of variability, especially in behavior or performance.)
対義語
stability (Focuses on something staying the same over time, with little or no variability.)
|
consistency (Emphasizes doing or being the same every time, the opposite of varying a lot.)

spread or dispersion in data
In statistics, how much numbers in a group are different from each other.
用法パターン：
variability of [data/measure]
よくある間違い：
Learners sometimes mix up "variability" with "variance" in statistics. "Variability" is a general idea of how spread out data are, while "variance" is a specific numerical measure. Learners may also incorrectly say *"the variability is 4"* when they mean "the variance is 4" or "the standard deviation is 2".
類義語
dispersion (A more technical word in statistics for how spread out data are; often used in phrases like "measures of dispersion".)
|
spread (A more informal, easy term used in teaching statistics to describe how far apart data values are.)
対義語
uniformity (Suggests data values are nearly the same, with very little spread or variability.)

differences within a species or population
In biology, how much members of the same species are different from one another.
用法パターン：
genetic variability in [a species/population]
よくある間違い：
Learners may confuse "genetic variability" with "genetic variety" or "biodiversity". "Genetic variability" focuses on differences in genes or traits within one species or population, while "biodiversity" usually refers to the number and variety of different species in an area.
類義語
diversity (Often used more generally for differences within a group; in biology it can overlap with variability but may also refer to number of species, not just differences within one species.)
対義語
uniformity (Suggests that individuals in a population are very similar, with little difference in traits.)
