1. Independent variable: The variable that is manipulated or changed in an experiment or equation. It is denoted by "x" in an algebraic equation.
2. Dependent variable: The variable that is affected by the independent variable in an experiment or equation. It is denoted by "y" in an algebraic equation.
3. Control variable: A variable that is kept constant in an experiment to ensure that only the independent variable is affecting the dependent variable.
4. Constant: A fixed value in an equation that does not change.
5. Categorical variable: A variable that represents categories or groups, rather than numerical values.
6. Continuous variable: A variable that can take on any value within a given range.
7. Ordinal variable: A variable that represents a ranking or order, but the differences between the categories are not necessarily equal.
8. Nominal variable: A variable that represents categories with no inherent order or ranking.
9. Discrete variable: A variable that can only take on specific, distinct values rather than a range of values.
10. Ratio variable: A variable that has a true zero point and meaningful ratios between values.
