What is true about correlation?

Correlation is a statistical measure that describes the relationship between two variables. It can range from -1 to 1, with 0 indicating no correlation, 1 indicating a perfect positive correlation, and -1 indicating a perfect negative correlation. Correlation does not imply causation, meaning that just because two variables are correlated does not mean that one causes the other. Correlation can be used to identify patterns and relationships in data, but it is important to consider other factors and conduct further analysis before drawing conclusions.

- Correlation is a statistical measure that describes the relationship between two variables.
- It is expressed as a number between -1 and 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation.
- Correlation does not imply causation.
- Two variables can be correlated without one causing the other.
- Correlation can be used to identify potential relationships between variables, but it is important to further investigate the relationship to determine if there is a causal link.
