1. Correlation indicates if there is any relationship between tow or more variables. SImple regression is a method which helps determine the relationship between a continuous output and one factor. The relationship is typically expressed in terms of a mathematical equation such as Y = b + mX
Multiple regression is a method which determines relationship between one dependent variable and multiple independent variables.

Example: To study if there is any relationship between temperature of environment where car is driven and battery performance. The performance of the battery can be measured by the number of miles driven from the ...
