Variable is a quantity or a characteristic that has or more mutually exclusive values or properties of objects or people that can be classified, measured or labeled in different ways.

**Types of Variables**

**Discrete Variable**– only a finite or potentially countable set of values.**Continuous Variable**– an infinite set of values between any two levels of the variables. They are result of measurement.**Independent Variable**– a stimulus variable which is chosen by the researcher to determine its relationship to an observed phenomena.**Dependent Variable**– a response variable which is observed and measured to determine the effect of the independent variable.**Moderate Variable**– a secondary or special type of independent variable chosen by the researcher to ascertain if it alters or modifies.**Control Variable**– a variable controlled by the research in which the effects can be neutralized by removing the variable.**Intervening Variable**– a variable which interferes with the independent and dependent variables, but its effects can either strengthen or weaken the independent and dependent variables.

**Characteristics of Variable**

1. Capable of assuming several values representing a certain category.

2. Values that may arise from counting and or from measurement.

3. Raw data or figures gathered by a research for statistical purposes.

4. Predicted values of one variable on the basis of another

5. Observable characteristic of a person or objects being studied.
