Pearson Correlation Coefficient
The Pearson Correlation Coefficient is a statistical measure that describes the strength and direction of the relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative relationship, 1 indicates a perfect positive relationship, and 0 means no relationship at all. For example, if we're looking at the relationship between hours studied and exam scores, a high positive correlation suggests that as study time increases, exam scores tend to increase as well. It helps us understand how closely related two sets of data are, aiding in predictions and analysis.

The Pearson correlation coefficient is a statistical measure that reflects the strength and direction of a relationship between two variables. It ranges from -1 to 1, where 1 indicates a perfect positive correlation (as one variable increases, so does the other), -1 indicates a perfect negative correlation (as one variable increases, the other decreases), and 0 means no correlation at all. This coefficient helps us understand how closely two sets of data are related, allowing for insights in fields like psychology, economics, and health research.
