Pearson Correlation

Pearson correlation is a statistical measure that expresses the strength and direction of a relationship between two variables. It ranges from -1 to 1. A correlation close to 1 indicates a strong positive relationship, where both variables increase together. A correlation close to -1 indicates a strong negative relationship, where one variable increases as the other decreases. A correlation near 0 suggests little to no relationship. This measure helps researchers analyze how closely related two sets of data are, aiding in understanding patterns and trends in various fields, such as science, economics, and social sciences.
