## What is Correlation Coefficient?

The Correlation Coefficient is a measure of how two variables are related. It is a number between -1 and 1 that indicates the strength of the relationship between the two variables. A positive correlation coefficient means that the two variables move in the same direction, while a negative correlation coefficient means that the two variables move in opposite directions.

## What is Correlation Coefficient Calculator?

A correlation coefficient calculator is a tool used to measure the strength of the linear relationship between two variables. It is a numerical value between -1 and 1 that indicates the extent to which two variables are related. A correlation coefficient of 1 indicates a perfect positive linear relationship, a correlation coefficient of -1 indicates a perfect negative linear relationship, and a correlation coefficient of 0 indicates no linear relationship.

## How to Calculate Correlation Coefficient?

The correlation coefficient is a measure of the linear relationship between two variables. It is calculated by dividing the covariance of the two variables by the product of their standard deviations. The formula for the correlation coefficient is: r = Cov(X,Y) / (σX * σY) Where Cov(X,Y) is the covariance of X and Y, and σX and σY are the standard deviations of X and Y, respectively.
