Variable are the attributes that can vary. In statistics, there are two main types of variables which are: qualitative variables and quantitative variables. A discrete variable is a kind of variable which has values of discrete points. It takes values from a finite set. It cannot have all the values within the limits of a variable. Discrete variables can contain only integers. Values with decimal point are not allowed in a discrete variable. It cannot have all the values on a real number line.
The values between two real numbers cannot be assigned in a discrete variable. It explains a finite number of conditions and takes values from finite set. Variables that take a finite number of values are called "discrete variables." Qualitative variables are categorized as discrete variables. Many quantitative variables are also discrete.
