The correlation coefficient (r) measures the strength and direction of a linear relationship between two variables. The magnitude of r indicates the strength of the correlation, while the sign indicates the direction. Both r = 0.48 and r = -0.48 have the same magnitude but different directions, indicating the same level of correlation strength but in opposite directions.
