3. Linear correlation: Linear correlation means when both variables changes in same ratio or constant ratio.
4. Non linear correlation: Non linear correlation means ratio of change in both variables is not same or constant and one variable is increases in same ratio but other do not increases in same ratio.
5. Simple Correlation: Simple correlation means when two variables are steady together.
