Understanding Correlation Coefficients
The correlation coefficient measures the strength and direction of a linear relationship between two variables. Values range from -1 to +1, where:
- +1: Perfect positive correlation (variables move in the same direction)
- 0: No linear correlation between variables
- -1: Perfect negative correlation (variables move in opposite directions)
Note that correlation does not imply causation - a strong correlation between variables doesn't necessarily mean that one causes changes in the other.
