The correlation coefficient formula measures the strength and direction of a linear relationship between two variables on a scatterplot. The formula is calculated as follows: r = (n * ∑(xy) - (∑x) * (∑y)) / (√(n * ∑(x^2) - (∑x)^2) * √(n * ∑(y^2) - (∑y)^2)), where r is the correlation coefficient, n is the number of observations, x and y are the variables, and ∑ represents the sum of the values. The correlation coefficient ranges from -1 to 1, with 1 indicating a perfect positive linear relationship and -1 indicating a perfect negative linear relationship.
Understanding the correlation coefficient formula offers numerous opportunities, including:
