👉 Correlation is a statistical measure that assesses how two or more variables are related to each other. It measures the strength and direction of the relationship between two variables, which can be positive, negative, or zero. The correlation coefficient ranges from -1 (perfectly negative) to 1 (perfectly positive), with values closer to 0 indicating a weaker relationship. Correlation is often used in statistics to analyze data, identify patterns, and predict future outcomes.
