Correlation coefficient is used in to measure how strong a connection between two variables and is denoted by r. Learn Pearson Correlation coefficient formula along with solved examples.
Pearson’s correlation coefficient formula produces a number ranging from -1 to +1, quantifying the strength and direction of a relationship between two continuous variables. A correlation of -1 means a perfect negative relationship, +1 represents a perfect positive relationship, and 0 indicates no relationship.
