Covariance: The Hidden Relationship Between Variables Revealed - legacy
Correlation measures the strength of a linear relationship between two variables, while covariance measures the co-variation. Although related, correlation and covariance are distinct concepts.
Covariance measures the tendency of two variables to co-vary, or move together. When two variables have a positive covariance, it means that when one variable increases, the other tends to increase as well. Conversely, when two variables have a negative covariance, it means that when one variable increases, the other tends to decrease. To illustrate, consider a simple example where the price of gasoline and the number of road trips taken are correlated. If gasoline prices rise, people may reduce their road trips, demonstrating a negative covariance between the two variables.
