There are two types of variables:
1. Continuous variables
2. Discrete variables
1. Continuous variables:
A continuous variable can be assume any numerical value. It may take integral values (1,2,3,4,5,6..) etc.,
2. Discrete variables:
A discrete variable can take only certain values. It jumps from one value to another and values are not continuous.
For example: Number of students in a class. Here students can be 50, 65,90,100 etc.,
