Pearson's correlation coefficient when applied to a population is commonly represented by the Greek letter ρ (rho) and may be referred to as the population correlation coefficient or the population Pearson correlation coefficient. The formula for ρ is: where, is the covariance, is the standard deviation of , is the mean of , and is the

Correlation Once the intercept and slope have been estimated using least squares, various indices are studied to determine the reliability of these estimates. One of the most popular of these reliability indices is the correlation coefficient. The correlation coefficient, or simply the correlation, is an index that ranges from -1 to 1. When the ...

30 – Correlation 1. The Pearson Correlation Coefficient Correlation You've likely heard before about how two variables may be correlated. While we use this word in an informal sense, there is actually a very specific meaning of the term in statistics. Correlation means that, given two variables X and Y measured for each case in a sample,
