1. product-moment correlation coefficient

In statistics, the Pearson correlation coefficient (PCC, pronounced ) ― also known as Pearson's r, the Pearson product-moment correlation coefficient (PPMCC), the bivariate correlation, or colloquially simply as the correlation coefficient ― is a measure of linear correlation between two sets of data. It is the ratio between the covariance of two variables and the product of their standard deviations; thus, it is essentially a normalized measurement of the covariance, such that the result always has a value between −1 and 1. As with covariance itself, the measure can only reflect a linear correlation of variables, and ignores many other types of relationships or correlations. As a simple example, one would expect the age and height of a sample of teenagers from a high school to have a Pearson correlation coefficient significantly greater than 0, but less than 1 (as 1 would represent an unrealistically perfect correlation).

1. product-moment correlation coefficient

The product-moment correlation coefficient, also known as Pearson's correlation coefficient, is a statistical measure that calculates the strength and direction of the linear relationship between two continuous variables. It is denoted by the letter 'r' and ranges between -1 and +1, where +1 indicates a perfectly positive linear relationship, -1 indicates a perfectly negative linear relationship, and 0 indicates no linear relationship.
