The coefficient of correlation describes the strength and direction of the relationship between two variables. It ranges from -1.0 to +1.0, where a value of -1.0 indicates a perfect negative correlation, 0 indicates no correlation, and +1.0 indicates a perfect positive correlation. It is not calculated as the square of the slope, and a value of 0.00 does not indicate that two variables are related.
