Meanings
A quantity or factor that can change, especially in experiments, statistics, or real-life situations.
A symbol (such as x) that represents an unknown value or a value that can change.

Definition
A variable is something that can change or have different values.
A variable is a factor, value, or condition that can change rather than staying the same. In math and science, it often means a symbol (like x) that can represent different numbers. In everyday language, it can describe anything that depends on changing conditions, such as the weather or people’s schedules.
Examples
- Price is a variable that depends on demand.
- In this equation, x is the variable.
- We controlled every variable except temperature.
- Her schedule is variable, so plans often change.
Common mistake
Learners sometimes confuse variable (something that can change) with variant (a different version of something).
