degree to which something changes

How much something changes instead of staying the same.

Brugsmønster: variability in [something]
Typisk fejl:
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.
Synonymer
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.)
Antonymer
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.)
Ordforbindelser

Eksempler
  • There is a lot of variability in the quality of the service between different branches.
  • Weather patterns have shown increasing variability over the past few decades.
  • The manager was worried about the high variability in weekly sales figures.
  • Customer satisfaction scores show considerable variability from month to month.
  • The teacher noticed great variability in how quickly students finished the exam.
Læringseksempler
  • There is big variability in the prices of houses on this street.
  • The weather here has a lot of variability, so you should bring warm and cold clothes.
  • We saw some variability in his work; some days it was good and some days it was poor.
  • There is less variability in temperature near the sea.
  • The doctor explained that there is natural variability in how people react to the medicine.

spread or dispersion in data

In statistics, how much numbers in a group are different from each other.

Brugsmønster: variability of [data/measure]
Typisk fejl:
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".
Synonymer
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.)
Antonymer
uniformity (Suggests data values are nearly the same, with very little spread or variability.)
Ordforbindelser
measure variability |reduce variability |explain variability |sources of variability |within-group variability |between-group variability
Temaer
statistics |science |research
Eksempler
  • The standard deviation is one way to quantify the variability in a data set.
  • High variability in test scores suggests that students are not performing at the same level.
  • We used mixed-effects models to account for variability between participants.
  • The researchers tried to minimize measurement variability by calibrating the instruments daily.
  • Most of the variability in income could be explained by education level and work experience.
Læringseksempler
  • The graph shows high variability in the test results.
  • We checked the variability of the measurements before we used the data.
  • Low variability means the numbers are close together.
  • The teacher talked about variability and average in the statistics class.
  • Scientists want to reduce variability in their experiments.

differences within a species or population

In biology, how much members of the same species are different from one another.

Brugsmønster: genetic variability in [a species/population]
Typisk fejl:
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.
Synonymer
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.)
Antonymer
uniformity (Suggests that individuals in a population are very similar, with little difference in traits.)
Ordforbindelser
genetic variability |phenotypic variability |environmental variability |population variability |individual variability |inter-individual variability
Temaer
biology |genetics |evolution |science
Eksempler
  • High genetic variability within a population increases its chances of adapting to environmental change.
  • The study examined morphological variability among different frog populations.
  • Climate change may reduce the natural variability of some plant species.
  • Inter-individual variability in drug response is a major challenge in clinical practice.
  • Low variability can make a species more vulnerable to disease outbreaks.
Læringseksempler
  • There is a lot of genetic variability in dogs, which is why they have many shapes and sizes.
  • Biologists study variability in a species to understand how it can change over time.
  • Low variability in a plant group can be dangerous if a new disease arrives.
  • The doctor said there is big variability in how people react to this drug.
  • Environmental changes can increase or decrease variability in a population.
