Correlation Coefficient Definition
A statistical measure that quantifies the strength and direction of the linear relationship between two variables is called the Correlation coefficient. Generally, it is denoted by the symbol ‘r’ and ranges from -1 to 1.
Correlation Coefficient Formula
Correlation Coefficient Formula: The correlation coefficient is a statistical measure used to quantify the relationship between predicted and observed values in a statistical analysis. It provides insight into the degree of precision between these predicted and actual values.
Correlation coefficients are used to calculate how vital a connection is between two variables. There are different types of correlation coefficients, one of the most popular is Pearson’s correlation (also known as Pearson’s R)which is commonly used in linear regression.
In this article, learn about the correlation coefficient formula, along with what is correlation, its types, examples, and problems.
