Calculating pearson's r in r

WebCorrelation coefficients are used to measure how strong a relationship is between two variables.There are several types of correlation coefficient, but the most popular is Pearson’s. Pearson’s correlation (also called Pearson’s R) is a correlation coefficient commonly used in linear regression.If you’re starting out in statistics, you’ll probably learn … WebCorrelation. The Pearson correlation coefficient, r, can take on values between -1 and 1. The further away r is from zero, the stronger the linear relationship between the two variables. The sign of r corresponds to the direction of the relationship. If r is positive, then as one variable increases, the other tends to increase.
