The correlation coefficient is a measure of the strength of the linear relationship between two variables. It can range from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation. In this case, the correlation coefficient is -0.6410, which indicates a moderate negative correlation between a car's age and its current value. This means that as a car gets older, its value tends to decrease.
