 Correlation coefficient

Correlation coefficient may refer to:
 Pearson productmoment correlation coefficient, also known as r, R, or Pearson's r, a measure of the strength of the linear relationship between two variables that is defined in terms of the (sample) covariance of the variables divided by their (sample) standard deviations
 Correlation and dependence, a broad class of statistical relationships between two or more random variables or observed data values
 Goodness of fit, which refers to any of several measures that measure how well a statistical model fits observations by summarizing the discrepancy between observed values and the values expected under the model in question
 Coefficient of determination, a measure of the proportion of variability in a data set that is accounted for by a statistical model; often called R^{2}; equal in a singlevariable linear regression to the square of Pearson's productmoment correlation coefficient
 Intraclass correlation, a descriptive statistic that can be used when quantitative measurements are made on units that are organized into groups; describes how strongly units in the same group resemble each other.
 Rank correlation, the study of relationships between different rankings on the same set of items
 Spearman's rank correlation coefficient, which measures how well the relationship between two variables can be described by a monotonic function
 Kendall tau rank correlation coefficient, which measures the portion of ranks that match between two data sets.
