The Linear Correlation Coefficient, often symbolized as 'r', quantifies the intensity and course of a linear association between two variables. It is computed by dividing the covariance by the result of multiplying the standard deviations. The coefficient can vary from -1, indicating an impeccable negative correlation, to 1, signifying an ideal positive correlation. A zero coefficient suggests there is no linear relation.
