variables

Things that change

Variables are quantities or elements that can change or vary.

In math and science, a variable represents an unknown or changeable value, typically symbolized by a letter: Solve for x.

In programming, variables store data that can be modified: The function takes two variables.

In experiments, researchers manipulate independent variables and measure dependent ones.

Figuratively, variables are unpredictable factors: There are too many variables to predict the outcome.
