A correlation is a mathematical relationship between two variables that reflects the changes between the variables. A correlation can be positive or negative. A positive correlation means that when one variable increases, the other variable also increases and vice versa. A negative correlation means that when one variable increases, the other variable decreases and vice versa.

This means that the relationship between the variables is more than just coincidental and that it really exists. A significant relationship means that a change in one variable is associated with a change in the other variable.

Regression analysis is a mathematical technique used to predict future outcomes and determine the relationships between different variables. It can be used to predict the effect of a particular influencing factor on another variable or to determine which variables contribute most strongly to a particular metric. Applications of regression analysis include predicting sales volumes, determining prices, and determining credit risk.
