Correlation and Covariance
- Positive correlation exists when larger values ofcorrespond to larger values ofand vice versa.
- Negative correlation exists when larger values ofcorrespond to smaller values ofand vice versa.
- Weak or no correlation exists if there is no such apparent relationship.
It is a measure that quantifies the strength and direction of a relationship between a pair of variables.
The correlation coefficient, or Pearson product-moment correlation coefficient is another measure of the correlation between data. You can think of it as a standardized covariance.
Make a Scatter Plot, and look at it! You may see a correlation that the calculation does not.Correlation Is Not Causation which says that a correlation does not mean that one thing causes the other.
