Pearson Product Moment Correlation Analysis. The sign or - of the correlation affects its interpretation. What is the Pearson product-Moment Correlation. Pearsons product moment correlation coefficient or Pearsons r was developed by Karl Pearson 1948 from a related idea introduced by Sir Francis Galton in the late 1800s. In statistics the Pearson correlation coefficient also referred to as Pearsons r or the bivariate correlation is a statistic that measures the linear correlation between two variables X and Y.
In terms of the strength of relationship the value of the correlation coefficient varies between 1 and -1. -03643187 09183058 sample estimates. Pearsons r measures the strength direction and probability of the linear association between two interval or ratio variables. The Pearson product-moment correlation coefficient Pearsons correlation for short is a measure of the strength and direction of association that exists between two variables measured on at least an interval scale. Correlation Pearson Kendall Spearman Correlation is a bivariate analysis that measures the strengths of association between two variables. When the correlation coefficient comes down to zero then the data is said to be not related.
