When do you use negative correlation in real life?

Negative correlation is used in real life to identify relationships where one variable decreases as another increases. For example, in finance, there is often a negative correlation between bond prices and interest rates; as interest rates rise, bond prices tend to fall. Similarly, in health studies, an increase in physical activity may correlate with a decrease in body weight. Understanding negative correlations can inform decision-making in various fields, including economics, health, and environmental science.
