1. Continuous variable:
If a variable can take any numerical value within a certain range, it is called continuous variable. It passes one value of the next.
2. Discrete variables:
If a variable can take only some particular value, it is called discrete variable. There are gaps between one value and the next possible one.
Example: continuous series:
