Pearson r. There is a simple and straightforward way to measure correlation between two variables. It is called the Pearson correlation coefficient (r) – named after Karl Pearson who invented it. It's longer name, the Pearson product-moment correlation, is sometimes used. The formula for computing the Pearson r …

(b) An example in which the full range of X and Y values shows a correlation near zero, but the scores in the restricted range produce a strong, positive correlation. A demonstration of how one extreme data point (an outlier) can influence the value of a correlation.

For example, suppose I decide to study the correlation between dose of alcohol (X) and reaction time. If I arbitrarily decide to use as values of X doses of 0, 1, 2, and 3 ounces of 190 proof grain alcohol and restrict X to those values, and have the equal numbers of subjects at each level of X, then I’ve fixed X and do a regression analysis.

The strength of prediction from a multiple regression equation is nicely measured by the square of the multiple correlation coefficient, R2 . In the case of only two predictors, R2 can be found by using the formula (7) In our example, we find

Understanding the Pearson Correlation Coefficient (r) The Pearson product-moment correlation coefficient (r) assesses the degree that quantitative variables are linearly related in a sample. Each individual or case must have scores on two quantitative variables (i.e., continuous variables measured on the interval or ratio scales).

Pearson Product Moment Correlation Coefficient , aka, Pearson r. A numeric measure of strength and direction of linear relationship between paired score values. r is a standardized quantity. A standardized measure whose value is always between -1 and +1 inclusive. So it doesn’t matter what size numbers you’re correlating.
