Calculating Correlation Coefficient In Python: A Statistical Measure
The correlation coefficient (r) ranges from -1 to +1, indicating the strength and direction of the relationship between two variables. It can be calculated using the formula: r = (n * (Σxy) - (Σx)(Σy)) / sqrt([(n * Σx² - (Σx)²) * (n * Σy² - (Σy)²)]).
In this blog post, we will explore how to calculate the correlation coefficient between two arrays. The correlation coefficient is a statistical measure that helps us understand the strength and direction of the relationship between two variables. Ranging from -1 to +1, this coefficient indicates whether the variables are positively or negatively correlated.
Understanding the Correlation Coefficient
The correlation coefficient ( r ) can be calculated using the following formula:
r = (n * (Σxy) - (Σx)(Σy)) / sqrt([(n * Σx² - (Σx)²) * (n * Σy² - (Σy)²)])
