The quantity whose different values during observation constitute the collection of data is called a statistical variable.

In collection A, the marks obtained by the students is a variable. If we denote the marks obtained by x then x is a variable in the collection.

A variable can be of two types.

**(i) Discrete variable:** A variable which can assume only a
finite number of values between two given values is called a discrete variable.

**For Example:** If x students for marks obtained then x is a
discrete variable for collection A because x takes only integral values from 4
to 90.

**(ii) Continuous Variable:** A variable which can assume all real values between two given values is called a continuous variable.

**For Example:** The height and the weight of a person are continuous variables.

**Note:** We will deal mostly which discrete variables.
