      • Correlation measures the relationship between two variables, indicating whether they tend to move together or independently. The strength and direction of the correlation are typically expressed using a correlation coefficient, with values ranging from -1 (perfect negative correlation) to 1 (perfect positive correlation). A correlation coefficient close to 0 indicates no relationship between the variables. In practical terms, correlation helps identify patterns and trends, allowing data analysts to make predictions and informed decisions.
