Correlations close to +1.0 or -1.0 indicate a strong relationship between variables, whereas correlations close to 0 indicate a weak relationship. Positive and negative correlations are both meaningful, as they indicate a relationship between variables that can be further explored. However, correlation does not indicate causation, meaning a strong correlation does not necessarily mean that one variable causes the other.
